Plasticity and Microstructure of Hot Deformed Magnesium Alloy AZ61

Abstract:

The article presents the results of tests connected with the influence of strain parameters on the change of flow stress and microstructure of magnesium alloy AZ61 (symbol according to ASTM norms). Test of uniaxial hot compression were conducted in temperature range from 250 to 400°C and the strain speed from 0.01 to 1 s-1. Analysis of plastometric tests and microstructure observation allowed to establish which mechanism - slip or twinning – is dominant in particular conditions of shaping AZ61 alloy. Achieved results were compared with previous results achieved for AZ31 alloy type with lower content of aluminium.
