Effect of Low Content Ca on the Microstructures and Mechanical Properties of AZ63 Alloys

Abstract:

Article Preview

The effect of low content of Ca (0.9 or less)on the microstructure and mechanical properties of AZ63 alloys were studied in this paper. The results show that, adding a small amount of Ca , the alloy does not generate Al2Ca phase. The calcium dissolved into the matrix or compound phase and have an uneven distribution, but it can improve the distribution of β-Mg17Al12 phase ,refine the grain and improve the mechanical properties. Adding 0.3%Ca to AZ63 (WT%), the microstructure and mechanical properties of alloy are more ideal.
