The Influence of Sr Addition on the Microstructure and Mechanical Properties of Aluminum Die-casting Alloys
School of Materials Engineering, Shanghai University of Engineering Science, Shanghai 201620, China
The effects of strontium addition on the microstructure and mechanical properties of aluminum alloys 380 and 413 are researched. All samples are prepared through high pressure die-casting, and the effect of the sample’s thickness is also compared. The results indicate that the Sr addition can refine the metallographic microstructure of two alloys in different degrees, mainly to eutectic Si phase. The mechanical properties of the two alloys are improved slightly through Sr modification to the thin wall castings. The enhancement of mechanical properties is evident to the thick wall castings.
