Effects of A-EMS on Microstructure and Mechanical Properties of DC Casting Al-10Si-1.1Ni Alloy

Abstract:

Al-Si alloys were characterized by excellent corrosion and wear resistance, low thermal expansion and high specific strength. Adding Ni to Al-Si alloy contributes to enhance the elevated temperature strength. However, the coarse structures and Ni-containing phases are disadvantageous for the mechanical properties. In this paper, an advanced melt treatment technology named the annular electromagnetic stirring (A-EMS) process was utilized for the Al-10Si-1.1Ni alloy to examine the effects of A-EMS on structures and mechanical properties. Research results showed that in the case of A-EMS, the billets with finer solidification structures and Ni-containing phases morphology as well as higher performance were achieved.
