CRYSTALLOGRAPHIC TEXTURE IN MG-ALLOY PLATE

Texture studies have been carried out on a Mg-2Zn-1Mn alloy plates as a part of the development of the fabrication process. The plates were hot rolled from cast ingots subjected to hammer forging. X-ray diffrac tion tehnique has been employed for texture determination using three specimens: normal direction (ND), rolling direction (RD) and transvers e direction (TD) from each plate. The textures have been characterised by inverse pole figures, direct pole figures and crystallite orientat ion distribution functions. The maximum basal (0002) pole intensity ha s been found to appear along ND of the plates. Basal slip is the domin ant mode of deformation in the material.
