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.

阐明镁合金的压缩成形极限对于扩大其在工业产品中的应用具有重要意义。采用应变路径可控的双向压缩装置，研究了镁合金在冷/温多轴压缩条件下的成形极限。考虑了断裂条件，几乎成功地建立了压缩成形极限准则。获得了初始各向异性和应变路径对压缩成形极限的影响等新的研究成果。
