Abstract:

Titanium and its alloys are widely used in industries due to their excellent comprehensive properties. However, their high-cost limits their applications in civil, therefore the research on low cost titanium technology is necessary. In the present study, the semi-solid deformation behavior of Ti14 burn resistant alloy was investigated. The results indicated that Ti2Cu melting phases within grains and at grain boundaries grow to form coarse grain boundaries and network structures during Ti14 alloy semi-solid deformation. Its microstructure was coarse and the grain boundary was wide after semi-solid forging, leading to low plasticity at room temperature. Recrystallizing heat treatment leads to fine microstructure, which is similar to that of conventional forging, resulting in improvement of tensile mechanical properties. The mechanical properties of semi-solid forging are similar to that of conventional one at high temperature.
