Research on the Selection of Heat Treatment Parameters of Casting Aluminum Alloy AlSi5Mg Type

Abstract:

The paper presents research on the effects of magnesium content on electrical and mechanical properties of materials after heat treatment of the casting of aluminum alloys: AlSi5Mg0.3, AlSi5Mg0.8 and AlSi5Mg1. The proposed heat treatment consisted of homogenisation at 535°C during period of the time 8 h, quenched to water and artificial aging at temperatures ranging from 120 to 240°C during period of the time to 24 h. Determination of strength properties were realized by Brinell hardness measurements. Electrical properties are in the form of electrical conductivity. The research program also included analysis of the microstructure of selected alloys.
