| Research Abstract |
Elucidation of compressive forming limit of magnesium alloys is quite important to enlarge their applications to wider industrial products. In the present study, forming limits of magnesium alloys under cold/warm multiaxial compressive conditions were investigated by using a unique strain-path controllable biaxial compression apparatus. The compressive forming limit criterion was almost successfully formulated by taking fracture conditions into consideration. The new research findings, such as influences of initial anisotropy and strain paths upon the compressive forming limit, were also acquired.
