摘要

利用数值分析技术研究了TC4钛合金在350℃

BC路径下1、2、4、6道次时等通道转角挤压过程中的载荷、温度、等效应力、等效应变受道次的影响变化。结果表明

随着挤压道次的增加

所需载荷增加

同时载荷的峰值也增加

并且出现的时间向后推移。温度升高

等效应力增加且等效应变增大。在挤压4道次后晶粒细化效果最明显。

Abstract

Effects of varied passes

such as 1

6passes

on loading

temperature

equivalent stress and strain of TC4alloy during equal channel angular extruding process were investigated with Bc path at350℃ by numerical analysis.The results reveal that with increasing in extruding passes

loading applied is increased

and the peak value of loading applied is increased with occurrence time shifted to right.With the increase of temperature

equivalent stress and strain are increased.In addition

the desirable grain refinement can be obtained in the TC4alloy with four passes extrusion.
