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


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.
