Influence of Aging Time on Mg-8Al-1Zn-3Ca Alloy

Abstract:

The microstructure and mechanical properties of Mg-8Al-1Zn-3Ca magnesium alloy aged for different time are investigated. With the increase of aging time, the high melting point intermetallic compounds Al₂Ca and Al₄Ca are increased obviously in number and the phase of Mg₁₇Al₁₂ has a dramatic decrease in number. The longer aging time results in a significant segregation phenomenon. The second phase becomes coarsen, and mechanical properties decline.
