Effect of Heat Treatments on Microstructure-properties and Ultrasonic Flaw Detection of Ti6242S Titanium Alloy

  • 摘要: 采用固溶时效及退火两种工艺对Ti6242S钛合金大棒材进行热处理,研究了不同热处理坯料尺寸对显微组织、力学性能以及探伤杂波水平的影响。结果表明:固溶时效态Ti6242S钛合金大棒材越靠近心部初生α含量越高,而退火态显微组织中等轴初生α相含量较固溶时效态更高;普通退火处理后蠕变性能较差,固溶时效态综合性能最好;固溶时效处理后大棒材水浸探伤底波的均匀性略有提高,而普通退火无此效果。
    Abstract: Ti6242S titanium alloy large bars were processed by solution-aging and annealing treatment. The effect of the sizes of the treated specimens on microstructure and mechanical properties as well as ultrasonic flaw detection was studied. The results indicated that the primary α content increased near the center for the STA specimen,and equiaxed α-phase content was higher in annealed microstructure than that in solution-aged microstructure; the creep resistance of Ti6242 S titanium alloy annealed was poor; the overall property was better by solution-aging treatment; uniformity of the ultrasonic flaw detection bottom wave on the alloy large bar solution- aged increased slightly,while ordinary annealing treatment brought no such effect.
