Effect of alloying elements on the microstructure and properties of AZ91 D-xCa-ySr

摘要：

　　In this paper,the microstructure and properties of AZ91D-xCa-ySr were studied by adding alloying elements.The mechanical properties were investigated by WDT-10 micro-electric universal testing machine and WD-T low cycle fatigue testing machine.The OLYMPUS-GX71 Optical electronic microscope,XRD and SEM were employed to investigate the microstructure of AZ91D.The results showed that the grains were refined by adding Ca,Sr,Gd and Y.Low cycle fatigue (LCF) behavior of AZ91D-0.4Ca-0.3Sr was improved obviously by adding 3.0%Gd and 3.0%Y into material,the tensile strengthen was up to 299Mpa,the elongation was 0.78%.
