The object of study was a commercial pipe magnesium Mg 3% Al 1% Zn 0.2% Mn (AZ31), hot pressed out at 430 ° C with a degree of deformation equal 9th Tube having an initial wall thickness of 4.5 mm and a diameter of 20 mm was then subjected to the process of rolling pielgrzymowego plunger. Before rolling, the material is heated to a temperature of 200 ° C. During the rolling deformation gradually increased up to approximately 55% reduction in cross-section. It has been observed that above 51% reduction of the deformation section the material began to crack and crumble. Therefore selected for further study of the deformation of the material up to 50%. Texture layers lying in the middle of the pipe wall thickness (Fig. 1) was determined on the basis of incomplete pole figures reflections (0001), (​​10-10), (10-11), (10-12) and (11-20) are registered dyfrakometru using D8 Discover X-ray, using radiation CoKα series. Measurements were made in the measuring grid równokątowej of α: 0 - 75 ° with a step Δα = 5 °. During the measurements used mikrokapilarę limiting the measurement area of approximately 3 mm, with the center of the area to coincide exactly with the axis of the tube. LaboTexTM using software, using the method of ADC was calculated orientation distribution function. Research metalograficznie and microhardness measurements were performed on longitudinal zgładach (RD-TD plane parallel to the longitudinal axis of the pipe). In this figure also shows the accepted frame of reference.
