Advanced processing methods for titanium

Abstract

Among the topics discussed are recent advancements in Ti near-net shape technology, vacuum hot pressing of large, near-net shape spar fittings, Ti alloy sheet forming, superplastic forming/diffusion bonding of Ti alloys, the influence of H additions on the high temperature superplasticity of Ti alloys, the effects of processing on the fatigue life of Ti-6Al-4V castings, and the laser welding of a Ti alloy. Also considered are aspects of speed machining of Ti, the microstructures and mechanical properties of laser-welded Ti alloys, and the failure characteristics of cutting tools for Ti alloy machining at high speeds.
