Effects of heat treatment on microstructure and mechanical properties of rolled AM50+xCa magnesium alloys
Effects of solution and aging treatment on microstructure and mechanical properties of rolled AM50+xCa alloys(x=0,1%,2%) were studied.The results indicated that with solution time increasing,Mg_(17)Al_(12) phase was dissolved into the Mg matrix and Al_2Ca phase became thinner and shorter,then gradually broken and began to spheroidize;with aging time increasing,Mg_(17)Al_(12) phase was precipitated from the Mg matrix as the form of small particles and Al_2Ca phase was stable and its shape and quantity changed little.After solution treatment,the alloy's hardness and tensile properties decreased.After the aging treatment,the alloy's hardness increased to its peak then decreased while the tensile properties increased a little.The solution and aging treatment can increase the ductility of AM50 and AM50+1Ca alloys.For AM50+2Ca magnesium alloy,the ductility increased after solid solution treatment and decreased after aging treatment.
