Microstructure and Mechanical Properties for TIG Welding Joint of High Boron Fe-Ti-B Alloy 作者:He, L (He Lin)[ 1 ] ; Liu, Y (Liu Ying)[ 1,2 ] ; Li, J (Li Jun)[ 1,2 ] ; Li, BH (Li Binghong)[ 1 ] RARE METAL MATERIALS AND ENGINEERING 卷: 43 期: 2 页: 283-286 出版年: FEB 2014 文献类型:Article 查看期刊影响力 摘要 The hot rolled plates of high boron Fe-Ti-B alloys were butt-welded by gas tungsten arc welding (TIG) using base metal as the filler. The microstructures of the TIG weld joints were analyzed. The results indicate that the welding quality of the high boron Fe-Ti-B alloys is very good, there are no obvious defects such as cracks, lack of fusion, incomplete penetration and strip defects in the butt weld joints. The microstructures of the weld metal and the heat affected zone are different from that of the base metal significantly. However, the micro-zone composition analysis indicates that the composition of the TIG weld joint is very uniform. Tensile tests were carried out on TIG welded joints after the post weld heat-treatment. The result shows that the welds have slightly higher yield strength (YS), and lower ultimate tensile strength compared to those of the base metal. However, the tensile properties reach a high level. The tensile strength of the high boron Fe-Ti-B alloys is higher than 580 MPa, and the yield strength is higher than 400 MPa. 关键词 作者关键词:high boron Fe-Ti-B alloy; TIG; microstructure; mechanical property KeyWords Plus:GRAIN-SIZE; STEEL; COMPOSITE; TITANIUM 作者信息 通讯作者地址: Liu, Y (通讯作者) 显示更多 Sichuan Univ, Sch Mat Sci & Engn, Chengdu 610065, Peoples R China. 地址: 显示更多 [ 1 ] Sichuan Univ, Chengdu 610065, Peoples R China [ 2 ] Minist Educ, Key Lab Adv Special Mat & Technol, Chengdu 610065, Peoples R China 电子邮件地址:zhibuyan@foxmail.com; Liuying5536@163.com 基金资助致谢 基金资助机构 授权号 Fundamental Research Funds for the Central Universities NCET-04873 查看基金资助信息 出版商 NORTHWEST INST NONFERROUS METAL RESEARCH, C/O RARE METAL MATERIAL ENGINEERING PRESS, PO BOX 51, XIAN, SHAANXI 710016, PEOPLES R CHINA 类别 / 分类 研究方向:Materials Science; Metallurgy & Metallurgical Engineering Web of Science 类别:Materials Science, Multidisciplinary; Metallurgy & Metallurgical Engineering 文献信息 语言:English 入藏号: WOS:000332750400006 ISSN: 1002-185X 其他信息 IDS 号: AC7YO Web of Science 核心合集中的 "引用的参考文献": 16 Web of Science 核心合集中的 "被引频次": 4 |
