The advantage of TMC compared with Ti-Al intermetallic compound is lower cost, better weldable property, simple fabrication process; lower density compared with super alloy. One of important demand of TMC sheet for high temperature application is used for higher speed craft with lighter part fabricated by SPF/DB technology. This paper illustrated TiBw/TA15+ TMC sheet fabrication and SPF/DB processing property, and analyzed effects of rolling processing on the microstructure and tensile properties. Wide sheet has been fabricated successfully. Forming mechanism of TMC is revealed, which is different from conventional titanium alloy, fined microstructure is unnecessary for TMC, four layers SPF/DB component also can be formed for TMC sheet.
