Effects of Combined Addition of Sc and Zr on Microstructure and Mechanical Properties of ZL 114A Alloy AITranslate
Abstract AITranslate
The effects of the combined addition of Sc and Zr on the microstructure and mechanical properties of ZL114A alloy were studied by polarized light microscope,DSC,SEM and Vickers hardness tester.The results show that for ZLll4A alloy with Al-Ti-B grain refinement,the nucleation temperature of primaryα-Al grains increases from 619.2 C to 621.6 C after the combined addition of Sc and Zr,and the number of nucleation cores also increases.The nucleation ofα-Al grains becomes easier and the grains are further refined,of which the size decreases by 9.8%from 319.2μm to 287.8μm.The combined addition of Sc and Zr has little effect on the eutectic Si of ZLll4A alloy,indicating that the change in mechanical properties of ZLl14A+Sc+Zr alloy is mainly attributed to the change in the size of primaryα-Al grains.After the combined addition of Sc and Zr,the hardness of ZL1l4A alloy increases due to grain refinement.
