Analysis of strain transfer through the Mg/Ti interface using crystallographic orientation analysis based on electron back-scattered diffraction patterns

Improvement of deformability for Mg-based composite materials with a dispersion of Ti particles has been considered in terms of the strain transfer through the interface, but is not fully understood during the deformation of ductile Ti particles. Mg-based composites composed of pure Mg and pure Ti plates was investigated to clarify the strain transfer through the Mg/Ti interface using crystallographic orientation analysis based on electron back-scattered diffraction (EBSD) patterns. It is suggested that the larger Schmid factor and lower residual strain energy (W) are significant for the operation of a prismatic slip system in the Ti grains.
