本文介绍了在受控实验室条件下无芯棒拉拔的铜管中的残余应力状态和织构。中子应力测定证实了从管壁的外表面到内表面的应力梯度。使用高能X射线分析管周边以及壁厚上的纹理梯度。管加工过程中的各向异性流动导致ODF分析所描述的纹理变化。
The residual stress state and the texture in Cu‐tubes, drawn without a plug under controlled laboratory conditions, are presented. Neutron stress determination confirms a stress gradient from the outer to the inner surface of the tube walls. High energy X‐rays were used to analyze the texture gradient around the perimeter of the tubes as well as over the wall thickness. Anisotropic flow during tube processing results in texture variations described by ODF‐analysis.
