Abstract Material selection and fabrication of metal fl at for titanium alloy hot forming and superplastic forming are introduced. Compared with heat resistant steels, superalloys are more suitable for fabricating the metal fl at. The producing technology of the metal fl at developed by Central Iron and Steel Research Institute (CISRI) has the advantage over the conventional technology. The homemade metal fl at made of K403 superalloy works stably, which shows that CSRI has capability of producing the metal fl at for titanium alloy hot forming and superplastic forming.
