Effect of Annealing Temperature on Microstructure and Properties of ATI425 Titanium Alloy Bars AITranslate
Abstract AITranslate
The annealing treatment of ATI425 titanium alloy bars in the range of 650~800℃was carried out at different temperatures.The microstructure,tensile properties at room temperature and Vickers hardness of the annealed ATI425 alloy bars were tested by metallographic microscope,universal testing machine and microhardness tester.The experimental results show that the yield strength and tensile strength of the ATI425 alloy annealed at 650℃decrease by about 30MPa,the elongation increases by 2%,and the Vickers hardness decreases by about 20 HV1 compared with those of the hot-working titanium alloy ATI425.When the heat treatment temperature is raised from 650℃to 800℃,the secondaryαphase in the alloy is equiaxly spheroidized,the primaryαphase grows up and the number of β phase decreases.Also the strength and Vickers hardness and microstructure is well at the annealing temperature controlled between 700℃and 750℃,which provides a reference for further production and application.
