EFFECT OF QUENCHING BY 30% POLYETHYLENE GLYCOL ON PROPERTIES OF Al-4.3%Cu-0.7%Fe-0.6%Mg ALLOY

Authors

Abstract
The Al-Cu aluminum alloys are primarily used in the aerospace industry as structural components. This study aim to improve properties of Al-4.3%, Cu-0.7%, Fe-0.6%, Mg alloy such as compression resistance, thermal stability and microstructure by quenching in 30% polyethylene glycol. Results showed that compression resistance improved by (10%) when quenching in 30% polyethylene glycol corresponding to the base alloy (quenching in water) when aging at 175 ºC for 3 hour. Also results showed that the thermal stability improved when quenching in polyethylene glycol.
