Effect of Composite Master Alloy on Mechanical Properties and Electrochemical Corrosion of ZL101 Alloy

摘要：

　　The mechanical properties and corrosion performances of the ZL101 alloy modified by the composite master alloy were investigated.The results showed that the master alloy had not only obvious effect of grain refinement,but also a significant role in refining dendrite grain of ZL101 alloy.The grain size decreased dramatically from 150μm to 62μm when the addition of composite master alloy is up to 0.5%(mass fraction) and the temperature is 720℃ for 30 minutes,.Its tensile strength and elongation increased by 27% and 42% respectively.The grain refinement of ZL101 alloy decreased its corrosion performance.The morphology of Si changed into globular from needle modified by NaF,instead of AlTiB.
