Abstract
This paper studied the hot deformation behavior of Ti-10Cu sintered alloy in order to optimize the deformation processing. Ti-10Cualloy was prepared by the powder metallurgy method to obtain strong antibacterial property. The deformation temperature range of 800°C to 1000°C and the strain rate range of 0.008 s−1 to 5s−1 were chosen. The constitutive equation in hyperbolic sin functionwas established and thehot processing map was drawn based on the true stress-true strain curves. The microstructure and of the hot deformed alloy were observed in order to reveal the influence of the hot deformation on the microstructure. The results showed that the Ti2Cu phase distributed homogeneously with increasing in the deformation temperature and decreased with the increasing of the strain rate. The final optimized deformation process was:a deformation temperature range of 850°C to 950°C, and a strain rate of 0.1s−1 to 0.5s−1, where a completely homogeneously distributed microstructure would be obtained.
