TC4钛合金对接板零件热成形工艺研究

摘要

TC4钛合金的屈强比高、弹性模量小，热成形是目前TC4钛合金零件成形的主要方法之一。热成形主要为了提高钛合金的塑形，减少零件的回弹。针对一种典型钛合金弯曲件对接板零件的热成形工艺进行了研究，在确定工艺方案的基础上完成了热成形模具的设计，并进行了相关试验，最终确定了对接板零件的热成形工艺参数并得到了符合图样要求的零件。%Due to the TC4 titanium al oy with the mechanical properties of high yield ratio and low elastic modulus, the hot forming becomes one of the most useful solution of it. The hot forming is used to improve the plasticity and reduce the springback of titanium. This paper focuses attention on the development of hot forming process for the TC4 titanium lap plate and designs the die based on the hot forming process. The qualified products are ultimately obtained with the optimized forming parameters .
