摘要
本文研究了热处理工艺对铸造IMI834高温钛合金组织及力学性能的影响。研究结果表明,IMI834高温钛合金铸态组织以集束状的片状α组织为主,热处理后的晶粒得到细化,适当的热处理制度可以有效提高合金的室温及高温强度。采用1020℃×1.5h,AC;700℃×2h,AC的双重退火工艺可以得到较理想的显微组织和良好的综合性能。
The effect of heat treatment on microstructure and mechanical properties of cast IMI834 titanium alloy was investigated in this paper.It is found that the proper heat treatment can improve the tensile strength effectively.The microstructure of the cast IMI834 mainlly composed of α colonies.The grain size became finer after heat treatment.The optimal heat treatment process of cast IMI834 titanium alloy is 1020℃×1.5h,AC;700℃×2h,AC.
