| Abstract: | The tensile properties of A357 casting aluminum alloy at TS/T6 themal treatment are investigated at room temperature. The experimental results show that at room temperature the mechanical properties of A357 - T5 casting aluminum alloy are slightly better than that of A357 - T6 casting aluminum alloy, and the mechanical properties of A357 casting aluminum alloy are much better than that of A356 casting aluminum alloy. The cast defects, dimples and secondary cracks are found on the fracture surfaces. |
