Effect of Surface Self-Nanocrystallization on Diffusion Bonding Between a Titanium Alloy and a TiAl-Based Alloy: 点击次数：; 发布时间： 2019-03-12; 发布时间：2019-03-12; 论文类型：期刊论文; 发表时间：2018-10-01; 发表刊物：JOURNAL OF MATERIALS ENGINEERING AND PERFORMANCE; 收录刊物：CPCI-S、SCIE; 卷号：27; 期号：10,SI; 页面范围：5551-5560; ISSN号：1059-9495; 关键字：diffusion bonding; self-nanocrystallization; TiAl alloy; Ti alloy; 摘要：A self-nanocrystallization layer was prepared on the surface of a Ti alloy sample via shot peening to investigate its influence on the follow-up diffusion bonding between a titanium alloy and a TiAl-based alloy. The experiment results show that surface self-nanocrystallization treatment can accelerate the interface reaction between a Ti alloy and a TiAl alloy, lowering the bonding temperature of the sound joints by more than 50K. Moreover, the thickness of the interface reaction layer plays an important role in the interfacial bonding strength. In this work, the maximum shear strength of the joint appears to have a thickness of about 1.8m. As a consequence, it is found that surface self-nanocrystallization treatment is helpful for optimizing the diffusion bonding process.
