During February I was focused on processing of the experimental data obtained from cubic ZrO2 samples. I did some 3D reconstructions which were used for visualization of grain boundaries network and pores morphology. Additionally, I calculated grain numbers, their sizes and level of porosity. Further calculations will be made in the future.

The minority carrier lifetime that is something that is not easy to characterize. It appeared that everything has an effect on this highly important parameter, e.g. size, orientation and distribution of grains, defects and microcracks of base material, also thickness, type of surface cover. However, measurement is essential if one wishes to determine the quality of the texture. The first attempt came out well. Waiting for more...

Main studies carried out during the month:

- preparation of an article for the AMT conference: „Microstructure and properties of AlMnFeCu and AlMnFeSi melt spun ribbons strengthened with quasicrystalline particles”
- preparation of an abstract: „Effect of Ti, Zr and Hf addition on microstructure and properties of rapidly solidified Al-Mn-Fe alloy” for the 20th International Symposium on Metastable, Amorphous and Nanostructured Materials (ISMANAM) 2013
- preparation of an abstract for a symposium „Materials Science for Industry” with the title „Quasicrystalline alloys Al-Mn-Fe obtained using rapid quenching – structure and properties”.
- additional training in SEM technique using PHILIPS XL30 X, Oxford Instrument equipment.
- some additional trials to perform thermomechanical analysis on melt spun ribbons (based on ternary composition as well as quaternary alloys with Hf, Zr, Ti and Mo addition).

In march I busied myslef with preparing an article for the upcoming AMT conference. I chose to discuss the relation between microstructure evolution and its influence on martenstic transformation temperature. DSC, XRD, SEM and TEM results are shown and discussed in detail in terms of grain growth and structure changes bewteen as cast, bulk and melt spun alloys.
