Multi-step wrought processing of TiAl-based alloys

[摘要] Wrought processing will likely be needed for fabrication of a variety of TiA1-based alloy structural components. Laboratory and development work has usually relied on one-step forging to produce test material. Attempts to scale-up TiA1-based alloy processing had indicated that multi-step wrought processing is necessary. The purpose of this study was to examine potential multi-step processing (ingot metallurgy-IM versus powder metallurgy-PM), intermediate alloys were examined. The results of the testing were then compared to samples from the same heats of materials processed by one-step routes. Finally, by evaluating the effect of processing on microstructure and properties, optimized and potentially lower cost processing routes could be identified. (C) 1997 Elsevier Science S.A.
