Experimental investigation on mechanical behavior of as cast Zn-Al-Cu/SiC/TiB₂ hybrid metal matrix composite by ultrasonic assisted stir casting technique

Abstract Now a days, the Zn-Al-Cu alloy-based composites have great impact on modern trends for bearing applications because of its reliable mechanical performance. In this paper characteristics as cast hybrid metal matrix been investigated, well influence reinforcements Silicon Carbide (SiC) and Titanium Diboride (TiB 2 ) composite. The ultrasonic assisted stir casting technique has adopted fabricating with addition dual like 5 wt% SiC constant by varying TiB 0 wt%, 10 wt%. ceramic particles are taken 20 30 microns in size. ASTM standards were used to conduct different tests, findings demonstrate significance adding alloy also noticeable increase performance terms hardness, tensile strength, young’s modulus strength. As Zn-Al-Cu/5 wt.% SiC/10 composite gives minimum density 4.79 g cc −1 maximum hardness 156Hv.
