摘要

采用OM、SEM和万能材料试验机研究了多次固溶和时效处理对Ti-53合金组织和室内力学性能的影响。结果表明:随着多次固溶和时效处理次数的增加，Ti-53合金的次生α片层数量、硬度、强度和塑性均在峰值后下降;在双固溶时效处理过程中，室内力学性能数值达到最高水平。多次固溶和时效处理能有效调节马氏体的形态，使具有不同Berlese矢量的马氏体片层合并或分解。因此，可以获得强度和塑性的良好匹配。

Multiple Solution and Aging Treatment Technology Improves Microstructures and Properties of Ti53 Alloy

The effect of multiple solution and aging treatment on microstructures and room-mechanical properties of Ti-53 alloy is studied by OM, SEM and universal material testing machine. The results show that the quantity of secondary α lamella, hardness, strength, and plasticity of Ti-53 alloy decrease after the peak value with the cycling times of multiple solution and aging treatment increasing. In the process of double solid solution aging treatment, the numerical values of room-mechanical properties reached the highest level. Multiple solution and aging treatment modulates morphology effectively, which can make martensite lamellas with different Berlese’s vectors merge or decompose. Therefore, the excellent match of strength and plasticity can be obtained.

期刊介绍： The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
