Texture evolution during deep drawing of Mo sheet

Texture evolution of the deep drawing of molybdenum sheet was investigated with EBSD (Electron Back Scattered Diffraction), X-ray diffraction techniques and orientation distribution function (ODF) analysis. The texture during deep drawing is hardly changed due to the strong of initial texture. Specimens symmetry of 45degrees from rolling direction have monoclinic symmetry during deep drawing process. EBSD can be used for the quantitative determination of macroscopic texture as like X-ray diffraction techniques if a. sufficient number of grains are measured. Grain sizes show the similar values during deep drawing process but their values along 45degrees direction from rolling direction at flange and wall are tend to increase. It is associated with the 45degrees earing of deep drawing processing. The correlation function values were -0.58 for RD flange and -0.36 for RD wall and suggest that high Taylor factor regions have low pattern quality and low Taylor factor regions have high pattern quality.
