| 摘 要： | 针对钛板在无张力条件下冷轧效率低下的问题,首先结合钛材力学性能各向异性的特点,以Hill异性屈服准则为基础,推导出钛板在张力冷轧下的应力状态方程,从而在理论上阐明,钛板在张力条件下进行冷轧的可行性主要取决于其塑性变形条件及其所处的应力状态.然后在实验室的四辊可逆冷轧实验机上对钛板进行了张力冷轧实验研究.实验结果表明,钛板在适当的张力作用下冷轧,能够在保证良好板形的前提下实现单道次大压下量轧制,极大地提高了轧制效率.

| Abstract: | The inefficiency problem during cold rolling of titanium sheet without tension exerted on it was investigated.The state equation of stress of titanium sheet under tensional effect is deduced on the basis of Hill's anisotropic yield criterion in combination with the anisotropic characteristics of titanium's mechanical properties.It was found theoretically that the feasibility of cold rolling of titanium sheet under tensional effect mainly depends on titanium's plastic deformation conditions and the state of ... |
