Microstructure and Mechanical Characterization of H-Al-Si Alloy Fabricated by Ultrasonic Vibration Assisted Stirring and Squeeze Casting – T6 Ageing

Meghavath Peeru Naik and Korabu Tulasi Balaram Padal

Abstract

The present research article presents the novel fabrication route of AlSi22-24Cu3.8Mg0.8 (H-AlSi22-24), an alloy made of silicon and aluminum using ultrasonic vibration stirring and squeeze casting. Al-Si alloys were prepared by varying the wt.% of Si from 22, 23, and 24. The goal of the study is to investigate the effect of wt.% of Si and ageing (T6) on the microstructure and mechanical properties of the UVSS alloys. The results present that the increase in wt.% of Si under UVSS modifies the microstructure and refines the primary and eutectic Si in the alloy. Ultimate tensile strength and yield strength of alloys were raised with increase in wt.% of Si and ageing treatment.
