摘要: Abstract We numerically study the rapid hardening and possible role of exhaustion twinning in magnesium alloys under dominated conditions, based on large strain elastic visco-plastic self-consistent model. It is found that upon tensile twinning, further deformation requires material to activate Prismatic Pyramidal slips, which have relative high critical resolved shear stress (CRSS). However, level at not enough slips. Consequently, imposed increments must mainly be accommodated by deformations, rate becomes a fraction modulus. Therefore, it can concluded composite response more associated with elasticity volume material, than dislocation-dislocation interactions normally held responsible for metals.
