Following tensile load increase the β→α″phase transformation and a″plate growth was clearly demonstrated.Owing to the SEM specimens were made of rather thin plates so the fracture was purely in ductile shear mode. The crack initiations took place on slip bands and the crack growth followed the re-nucleation and coalescence manner.DIC optical microscopy was used to identify the slip lines and a″plates.Correspondent: ZHU Weidou, associate professor, Department of Materials, Xi′an Jiaotong University, Xi′an710049 Key words： Ti-10V-2Fe-3Al    in situ tension observation 收稿日期: 1994-10-18      基金资助:国家自然科学基金 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 朱维斗 顾海澄 郭延东 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1994/V30/I10/463 1李青云．第六届全国钦及钛合金学术交流会文集(1),1987:12DueringTW,MiddletonRM,TerlindeGT,WilliamsJC．Titanium′80,V．2:15033宋书娟．西安交通大学硕士论文,19894JeffreyR,BiedrmanRR．Titanium′80,V．2:4915LiebowitzH．AnAdvancedTreatiseI．NewYork:AcademicPressInc,1968:3356BroekD．ElementaryEngineeringFractureMechanics,3rdreviseded,Hague:MartinusNijhoffPublishers,1983:38 [1] 杨蕊,潘艳,陈威,孙巧艳,肖林,孙军. 微尺度Ti-10V-2Fe-3Al单晶压缩变形行为及其微观机制*[J]. 金属学报, 2016, 52(2): 135-142.
