Effects of Heat Treatment on Microstructure and Mechanical Properties of Mg-3Sn-2Ca Magnesium Alloy

Abstract:

The effects of heat treatment on the microstructure and mechanical properties of Mg-3Sn-2Ca alloy were investigated. The results indicate that after solutionized at 500 °C for more than 24 h, the morphology of the CaMgSn phase in the alloy changes from the continuous and/or quasi-continuous nets to the particle-like shape. Furthermore, after solutionized at 500 °C for 24 h, for a given aging temperature of 285 °C, with prolonging aging time the matrix hardness of the alloy increases, and attains the maximum at 32 h of aging time and beyond that it decreases. In addition, it is preliminarily inferred that heat treatment would give a beneficial effects on the tensile and creep properties of Mg-3Sn-2Ca alloy due to the modification of the CaMgSn phase.
