本文研究了两种晶粒组织的二元Al-Li 合金拉伸性能与断裂行为。结果表明Al-Li 合金力学性能与晶粒尺寸有关,其断裂行为决定于PFZ 内平面滑移或晶界沉淀相与滑移的交互作用。
Tensile properties and fracture behavior of a binary Al-Li alloy with twogroups of different grain size have been investigated.The properties are affected by thegrain size of alloy,and improved as the grain become small.The fracture behavior is closelyrel
