Crystallographic textures

Abstract

Abstract. In material science, crystallographic texture is an important microstructural parameter which directly determines the anisotropy degree of most physical properties of a polycrystalline material at the macro scale. Its characterization is thus of fundamental and applied importance, and should ideally be performed prior to any physical property measurement or modeling. Neutron diffraction is a tool of choice for characterizing crystallographic textures: its main advantages over other existing techniques, and especially over the X-ray diffraction techniques, are due to the low neutron absorption by most elements. The obtained information is representative of a large number of grains, leading to a better accuracy of the statistical description of texture.

Overcoming challenges in using magnesium-based materials for industrial applications using friction-stir engineering

“…The low plasticity leading to poor workability is primarily attributed to the anisotropic mechanical properties of deformed Mg alloys, hence restricting their application. Mg having H.C.P structure possesses highly anisotropic mechanical properties, owing to the restricted number of deformation modes existing to hold deformation [5][6][7][8]. These low mechanical properties can be ascribed to the anisotropic behaviour and higher difference in critical resolve shear stress between the different planes of Mg.…”
