Fabrication and superplastic forming property research of TiB whisker reinforced titanium alloy matrix composite sheet

Abstract. Applied at elevated temperature compared with in situ-whisker reinforced titanium matrix composite(TMC) higher than alloy 50~150℃. The advantage of TMC Ti-Al intermetallic compound is lower cost, better weldable property, simple fabrication process; density super alloy. One important demand sheet for high application used speed craft lighter part fabricated by SPF/DB technology. This paper illustrated TiBw/TA15+ and processing analyzed effects rolling on the microstructure tensile properties. Wide has been successfully. Forming mechanism revealed, which different from conventional alloy, fined unnecessary TMC, four layers component also can be formed sheet.
