Abstract：The distribution of deformation in the section of tube rounds during Man-nesmann piercing has been experimentally studied with a view to establishing itsmechanism. It was shown: 1. The distribution of the intensity of strain across the diameter of a tuberound is inhomogeneous with W-shaped. The intensity of strain on the sur-face layer and centre layer is stronger than that on the intermediate layer. 2. Its inhomogeneity increases during the process. 3. Distinct deformation at the centre of the tube rounds has taken place be-fore the cavity occurs, so that the fracture is tough. 4. It is proved that the results obtained by adopting three experimental meth-ods are very alike. 收稿日期: 1980-04-18      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 卢于逑 王先进 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I4/470 [1] Seibel, E., Stahl Eisen, 47 (1927) , 1685． [2] Kocks, F., Stahl Eisen, 47 (1927) , 433． [3] #12 [4] #12 [5] #12 [6] #12 [7] #12 [8] #12 [9] 王先进,斜轧穿孔时金属的变形--断裂机构,北京钢铁学院研究生毕业论文,1963． [10] 卢于逑,王先进,朱景清,胡文耀,用硬度测定法研究料轧过程中金属的变形分布,中国金属学会压力加工学术会议报告,1962． [11] 卢于逑,王先进,斜轧穿孔过程中应力和变形的分布和中心金属断裂机构的某些特点分析,北京钢铁学院研究生专题论文,1963． [12] 张作梅,黎俊结,金属学报,7(1964) ,43． [13] 加藤健三,第23回塑性加工连合讲演论文集,北九州,1972,p.237． [14] #12 [15] #1 No related articles found!
