The influence of hydrogen on chip formation in cutting Ti-6Al-4V alloys: 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：2017-03-01; 发表刊物：INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY; 收录刊物：Scopus、EI、SCIE; 卷号：89; 期号：1-4; 页面范围：371-375; ISSN号：0268-3768; 关键字：Hydrogen treatment; Ti-6Al-4V; Machining; 摘要：The paper investigated how hydrogen, introduced via thermal diffusion, influenced the formation and morphology of chips formed by cutting Ti-6Al-4V alloys. The chips' microstructure and characteristics were studied by using optical microscopy (OM), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Experimental results demonstrated that with an increase in plasticity, the lamellar chips transformed to saw-tooth chips. Metallurgical analysis suggested that the saw-tooth chips formed because of thermoplastic instability caused by large plastic deformation. In contrast, the lamellar chips formed because of crack initiation.
