performance of TC25 titanium alloy ring
研究两种TC25钛合金环材的β锻造工艺,分析两种方案生产的环材纵剖面宏观组织,端面、内壁、外壁显微组织和力学性能的差异。结果表明:在环材制坯工艺一致的情况下,在最后一火成型时采用相变温度以上20~50
℃、变形量在40%~55%的锻造工艺,可生产出性能满足使用标准要求的d 450/d 350 mm×60 mm TC25钛合金β锻造环材。
Two different β-forging methods for manufacturing d 450/d
350 mm×60 mm TC25 titanium alloy ring were studied, vertical section structure.
The difference of microstructure and mechanical property of transverse section,
internal and outside wall was analyzed. The results show that, when the same
forging procedure is adopted in the last forging molding process, the
temperature is above phase transformation points 20 to 50 ℃, and the deformation
is between 40% to 55% in the forging procedure, TC25 titanium alloy ring with
size of d 450/d 350 mm×60 mm can be produced, whose excellent performance meets
the requirements of the corresponding employ standards .
