Abstract:The microstructures and mechanical properties of ZTC4 cast titanium alloy under different conditions were studied. The results show that the general properties of ZTC4 cast alloy are improved after HIP, the scattering degree of mechanical properties is reduced. The mechanical properties of ZTC4 by forging are much better than these by casting or HIP.
