Experimental Correlation between Metallurgical Parameters, Hardness and Drilling Force and Moment of Al-Si Alloys

Abstract:

The present study was undertaken to investigate the effect of alloying additions and aging parameters (time and temperature) on the hardness and machinability of Al-Si alloys. Hardness, drilling force and moment and number of holes drilled/tool measurements were carried out on specimens prepared from grain refined, Sr modified and heat treated Al-Si alloys. Aging treatments were carried out for the as solution treated (SHT) specimens (after quenching in warm water) at different conditions. Hardness, drilling force and moment and number of holes drilled/tool as a function of different metallurgical parameters are analyzed to acquire an understanding of the effects of these variables and their interactions on the hardness and machinability of heat treated Al-Si alloys.
