| Abstract: | In order to obtain the best mechanical properties of ZTC4 alloy casting,effects of hot isostatic pressing treatment parameters(temperature,time and pressure) on microstructure of ZTC4 casting titanium alloy were investigated systemically.The results show that the room temperature tension and bend properties are obviously affected by the hot isostatic pressing treatment parameters,especially the elongation of ZTC4 alloy,but the impact property is affected slightly.The casting show the best mechanical properties when they are HIP at 920℃ for 2h with the pressure of 125MPa,by consideration of all the conditions. |
