【摘要】 钛合金具有比强度高的特点,可替代铝合金和合金钢。钛合金的变形抗力和屈强比较大,其壳体室温变薄旋压成形有一定困难。为了探讨钛合金旋压的可行性,在热模拟压缩试验的基础上,分析钛合金加热变形过程,为钛合金加热变薄旋压工提供了参考。试验结果显示钛合金合理的旋压温度为650-750℃,因其不是应变速率敏感材料,可根据各道工序的需要改变转速和进给速度。更多还原

【Abstract】 Titanium alloy exhibits the property of high strength-to-rigidity. It provides potentiality to replace aluminum alloy and alloy steel. Generally, it is difficult to spin titanium alloy at room temperature, because of its high deformation resistance and yield-to-tensile ratio. In this paper the feasibility of tube spin-ning titanium alloy was analyzed based on the experimental results of hot compressive deformation test. The results show that the proper spinning temperature of this alloy is about 650 - 750 ℃ . The feed rate and rotating speed should be determined by each technical step since it is not strain rate-sensitive material.更多还原
