The hot metal plastic forming technology is an effective manufacturing method to produce the thin-walled parts with complex curved surfaces of the titanium alloy and some other difficult-to-machine materials

including hot pressing forming

creep/stress relaxation forming

hot gas forming

superplastic forming and diffusion bonding

hot flexible forming

and so on. The hot deformation mechanism of titanium alloy is the theoretical basis for the hot metal forming technology. The shapes and performances of the titanium alloy can be coordinately controlled under the appropriate process parameters. The research processes of hot forming technologies

typical defects and their solutions

moulds and high-end hot forming machine tools are summarized. The development trend of titanium alloy thin-walled parts is forecasted.
