| Abstract: | The temperature incremental solution heat treatment of 7075 alloy was investigated to elevate the solution temperature limit for enhancing the solution of the soluble remaining constituents. It was discovered that temperature incremental treatment can make the limit solution temperature higher than the multi phase eutectic temperature without the formation of overheated structure, effectively enhance the solution and improve the mechanical properties of the 7075 alloy. By the enhanced solution, the yield strength and ultimate tensile strength of 7075 alloy rise to 606 MPa and 660 MPa respectively. [ |
