Paper Title:
Mechanical Properties and Microstructure of AM140 Magnesium Alloy
  Abstract

The homogenization treatment, hot extrusion, and annealing treatment are carried out to study the effects of these processes on the mechanical properties and structure of AM140 magnesium alloy. The parameter of homogenization treatment (420°C× 24h) determined by DSC and metallurgical photo is sufficient which ensures the eutectic phase melt into magnesium matrix greatly. The Rm, Rp0.2 and A of billets after hot extrusion are 355MPa, 305MPa and 3.5% respectively. The variation of structure and mechanical properties during the process of aging is also studied by optical observation and tensile strength .
