Abstract

The Al–Si-Cu-Mg alloy as potential high temperature materials for automobile industry, the mechanical properties of alloy was inspected at distinctive temperatures from ambient to 350 °C. Al–Si-Cu-Mg alloy was made by stir casting technique. Microstructural studies showed that sensibly uniform distribution of silicon particles. It was found that the tensile behavior of alloy was decreasing with increasing of temperature. The effect of temperature on tensile behavior of the alloy had been surveyed and it revealed that behavior of Al–Si alloy changed from ductile to brittle mode with extension of temperature condition.
