The Evolution of Heat Treatment on the Tensile Properties of Na-Modified Al-Mg₂Si In Situ Composite

Abstract:

The effect of different solution temperatures has been investigated on the tensile properties of Na-modified Al-Mg₂Si in situ composite specimens which were subjected to solutionizing at different temperatures of 480 °C, 500 °C and 520 °C for holding time of 4 h followed by quenching. Tensile test results indicated that elongation value gradually increases upon solution treatment whereas ultimate tensile strength (UTS) reduces. The results of solution treatment also showed that the highest quality index is achieved in 500 °C (354 MPa) and so it is revealed optimum solutionizing temperature level (500 °C) for improving tensile properties.
