Manufacturing Process Development of SUMITOMO Beta Titanium Alloy 'SAT-2041CF' with Excellent Cold Formability

摘要

In this paper, several properties of beta titanium alloy "SAT-2041CF" are described for manufacturing process development. The results are as follows: 1) Solution treatment condition of this alloy should be determined to consider recrystallization and grain growth. Recrystallization of the cold rolled sheet is completed within 40s at 1173K. However, the rolled structure remains even after 1160 s at 1023K. 2)Serious oxidization occurs in atmosphere heating due to the high vanadium content.
