A few remarks on the Programme based on PhD students opinions and discussions with Lecturers

After completing the first year of PhD studies entitled: Interdisciplinary PhD Studies in Materials Engineering with English as the language of instruction, the following suggestions have been made by the Leaders of the Project, lecturers and the PhD students. These suggestions and comments appeared to be very helpful in revising the programme. Especially, the contribution of PhD students to the revision the programme seemed to be particularly valuable in elaborating a series of lectures which should be most profitable for Final Beneficiaries.

The main revisions in the current programme are as follows:

Year 1:

  1. Course Introduction to materials science will be shifted from Semester II to Semester I.

Year 2:

1. Course: Transmission electron microscopy in materials science will be shifted from Semester II to Semester I

2. Course of Foreign language will start in Semester II (30 hours)

3. There will be Practical Sessions dedicated to Scanning Electron Microscopy (5 hours), Transmission Electron Microscopy (5 hours ) and X-ray Diffraction (5hours) held in the laboratories under supervision of experienced staff.

Year 3:

  1. Course: Commercialization of scientific research will be shortened to 10 hours (instead of 15 hours)
  2. It is planned to add a course entitled: Electrochemistry for materials science in Semester I (10 hours)
  3. It is planned to add a course entitled: Renewable energy technologies in Semester II (10 hours)

The final topics and a short description will be given in due course when the final agreement will be reached with potential lecturer.

An additional condition is introduced to the Programme.

PhD procedure will be launched after completing Semester II of the Year 3 of the Studies at the latest. The procedure begins with the PhD seminar during which the student is obliged to presents a substantial progress of the PhD thesis.

Introduction

The PhD programme is organized into four main areas, i.e.:

1. Environmental-friendly materials and technologies

· Lead-free solders

· Multicrystalline silicon solar cells

· Biocompatibile coating in blood contacting materials

2. Knowledge-based multifunctional materials

· Gradient materials produced using different methods

· Light alloys of new generation with improved mechanical properties

· Production and optimization of intermetallics properties

· Bulk metallic glasses

3. Nano- and microcrystalline materials

· Mechanical alloying and hot-pressing of intermetallics

· Severe plastic deformation and fabrication of ultra-fine grain materials

4. Development of modern research tools and diagnostic methods

· Crystallographic orientation mapping in respect to diagnosis and prognosis of mechanical properties of metallic, ceramic and composite materials based on the scanning and transmission electron microscopy examinations of local grain orientations

· Data processing of local crystallographic orientations; orientation distribution function, orientation topography, quantitative description of microstructure

· Complex characteristics of advanced materials using new transmission electron microscopy techniques.

The above fields are only roughly defined. Each member of the Institute scientific staff works in at least two of these fields and a number of subjects appear simultaneously on the lists of research subjects. There is a great deal of interaction between the fields.

Students are expected to learn fundamentals of their chosen field and to develop a deep understanding of one their significant aspects. Students are required to take further subjects designated by their academic advisor. A full range of advanced-level subjects is offered in each field, and arrangements can be made for individually planned study of any topic. Oral examinations in the academic programme for the doctoral degree are designed accordingly. Participation in all Institute seminars is obligatory.

Presently, a large research programme on the structure and properties, preparation, and processing of materials, with emphasis on ceramics, metals and biomaterials, is conducted in the Institute. Students choose research projects from several possibilities that exist within the Institute and work closely with its scientific supervisor. The results of the thesis must be of sufficient significance to warrant publication in the scientific periodicals.

The Institute of Metallurgy and Materials Science has a number of well-equipped research laboratories. There is a close interaction between them including the sharing of experimental facilities and equipment. Most of experimental facilities are extensively used in the frame of Testing Laboratories authorized by Polish Centre for Testing and Certification in accordance with ISO standards. The certificate of conformance with Polish and European standards PN-ISO/IEC 17025:2001 for testing methods in the range of mechanical and structural properties of metals and alloys is valid till the next audit in 2012.

Seminars how to write scientific papers and prepare PhD thesis

(15 hours, credit)

Seminar summary

The seminar is aimed at discussing different ways of presentation of results of investigations to scientific community. The discussion of final, partial or even preliminary results with other specialists in the field is one of most important thing in reaching the right solution of the analyzed problem. Presently, scientists may communicate through different channels, like seminars, conferences, international congresses, aside from writing papers to scientific journals. There are well defined rules which such communications should fulfill, i.e. they should be divided to parts which enable easier understanding of their content. Additionally, each part should include strictly pre-defined information. However, all these possibilities require significantly or at least slightly different approach. The presentation of results should be clear and as short as possible but simultaneously properly backed with experimental data. The overview of the field justifying both the start of experiment and publishing its results is one of most important thing. The discussion of results needs its verification in papers listed in overview. All this should be well balanced to make a good paper. The specified above concept of sharing results was elaborated to help to understand each other results. Of course, these rules might be changed in some special case, but such situation should be well documented and explained. Therefore, the present seminar will explain the most important points which should be considered, while writing abstracts, extended abstracts, short communications, and full length papers. Finally, the proper arrangement of Ph. D thesis, i.e. presentation based on only most important results form a study including a four of five years will be proposed.

Course summary

Electrochemical processes find a wide variety of applications for the surface treatment. They include cathodic and anodic processes e.g. electroplating, anodization, electropolishing etc. Especially, in the last decade, electrodeposition technology is becoming increasingly important. It is suitable for manufacturing of functional and decorative coatings. Metals, alloys and metal matrix composites are deposited for the fabrication of single films or multilayer coatings with enhanced properties. For an understanding of the technical and practical demands of electroplating technology the theoretical knowledge of the phenomena occurring in electrolyte solutions and at the interface cathode / electrolyte is necessary. Lectures concern of these problems, however they refer only to aqueous solutions. The course is presented in a logical and practical order.

Course: Selected problems of microstructure and texture transformations in deformed metals

(10 hours, exam)

Course summary

A series of Courses briefly recalls the basic description, definitions and elementary constitutive laws used to describe plastic deformation. Then it covers a description of work hardening at relatively low temperatures (where thermally activated processes do not play a key role) followed by the analysis of some important features of plastic deformation significant for large strains (Course 1 & 2).

Softening processes (recovery, recrystallization and grain growth) and associated microstructural changes will be discussed based on driving force and involved mechanisms. This part provides an overview of several essential parameters including: stored energy of deformation, surface energy and the movement of high-angle boundaries (Course 3).

Course 4 will be dedicated to the description and interpretation of crystallographic textures. After an introduction to the ‘world’ of graphical representation of texture data, a short survey of the most important cold deformation and recrystallization textures will be presented.

Course 5 will be dedicated to techniques of local orientation measurements based on TEM and SEM techniques. The influence of band like strain inhomogeneities of deformation, their crystallographic nature and role in texture transformation in fcc metals will be thoroughly discussed.

A broad overview on modern coating and thin-film deposition technique is presented. The major aim of these Courses is to show and discuss various problems of physics and chemistry involved in the production, characterization and applications of coatings and thin films, which can be variously hard and wear resistant. Attention is paid at the bio-medical coating for tissue contacting materials. A balance is found between fundamentals aspects and experimental results illustrating various models, mechanisms and theories. New trends and new results are also evoked to have an overlook about future developments and applications.

Course: Crystal diffraction and diffraction based methods of orientation and strain determination

(10 hours, exam)

Course summary

In the research on (poly)crystalline materials, it is frequently necessary to investigate orientations of crystals (or crystallites) and geometry of the crystal lattice. In particular, crystal orientations and strains are determined locally to create orientation or strain maps. These techniques rely on electron and X-ray diffraction.

The course will be focused on means of getting orientations and strains based on diffraction

patterns obtained from individual crystals. To calculate orientations or strains, intermediate steps like pattern indexing or determination of lattice parameters are necessary. A comprehension of all computational stages leading to orientations and strains requires some notions from geometric crystallography and a thorough understanding of diffraction by crystals. Both fields will be covered at the outset of the course. Then, we will proceed to algorithms for indexing, lattice parameter determination, and for computation of orientations

and strains. At the end, example packages of relevant software will be presented.
