Study on Mechanical Property of a New Super-high-strength Aluminum Alloy AITranslate
Abstract AITranslate
Based on differential thermal analysis(DTA),metallurgical structure observation.cold tensile test, optical microscope and scanning electron microscope(SEM) observation, analysis is made of the effect of different solid-solution processes on the microstructure and mechanical properties of high-Zn Al-10.4%Zn-2.2%Cu-2.4%Mg-0.1～0.15Zr-0.224%Ag alloy.The results show that the use of intensified solid solution process at almost low-melting-point eutectic fusion temperature and single-stage ageing can result in remarkably better mechanical property than that by single-stage solid solution and low-temperature intensified solid solution with tensile strength>770Mpa and about 8% to 10% elongation.Compared with other domestic 7000-series alloy,it has super-high strength and good plasticity, indicating that proper solid solution process can result in good coordination of the strength and plasticity in the highly-alloyed super-high-strength Al alloy.However,the SEM observation shows that certain number of coarse second phase particles remained in the solution structure,as will bring about negative impact on the overall properties of the alloy . Thus,further optimization is to be done on the solid solution.
