摘要：

A strengthening process for a TC4 (Ti-6Al-4V) titanium alloy is presented, consisting of ''High Temperature Forging+High Temperature Solution Treatment+Conventional Annealing'', and the mechanism of strengthening is discussed. Experimental results indicate that this new process can increase the room and high temperature strengths strikingly without reducing the ductility and thermal stability. Based on microstructural analyses, it is concluded that the most effective strengthening for the TC4 alloy is the ''boundary layer'' strengthening rather than the more commonly considered dispersion and/or solution strengthening.
