Ti-15-3 合金的超塑性及应用

Superplasticity and Applications of the Ti153 Alloy

研究了Ｔｉ－１５－３钛合金薄板退火状态和冷轧状态的超塑性，ｍ值均在７００℃出现峰值，达０．４，延伸率为２６０％。冷轧箔材在７００℃可吹塑成形复杂构件，并可获得优良的力学性能。该构件在卫星上得到应用。

The superplastisity of the Ti153 titanium alloy sheet in annealed and cold rolled conditions has been investigated The peak values of m appear at 700℃ in both conditions up to 04 Elongation is 260% The cold rolled foil can form complex parts at 700℃ by superplastic forming and the excellent mechanical properties have been obtained This part has been used on the satellites
