Effect of solution and aging technology on microstructure and properties of ZA27 alloy

Wu Yue

Abstract

Effect of solution treatment on microstructure and mechanical properties of ZA27 alloy were studied by means of scanning electron microscopy(SEM),X-ray diffraction(XRD) and mechanical property testing.After solution treatment in the temperature range of 300-380 ℃ for 1 h,the alloy samples were aged at 160 ℃ for 8 h.The results show that complete dissolution of the solute atoms in the ZA27 alloy is obtained after solution treatment at 365 ℃ and uniformly distributed fine precipitates are observed after aging treatment.The proper solution treatment parameters of the alloy are heating at 365 ℃ for 1 h.
