Compressive Deformation of Cast AM60B Mg Alloy at Elevated Temperatures
The deformability of cast AM60B Mg alloy is investigated by compressing AM60B cast ingots at elevated temperatures. The empirical results show that cast AM60B Mg alloy was brittle at room temperature and prone to cracking during compression, however at the temperatures ranging from 573 to 673K, excellent deformability is demonstrated with around 70% compression ratio. The compressive deformation constitutive equation for AM60B Mg alloy at elevated temperatures was established. The stress-strain relationships predicted at elevated temperatures show good agreement with experimental findings.
