摘　　要：在Gleeble-1500热模拟机上进行了TC4钛合金压缩试验,分析了不同温度、不同应变速率下TC4钛合金热力学行为,确定了合金棒材最佳开轧温度为950℃,最佳应变速度为1s-1。随后在自行研制的八机架Y型轧机上进行连轧试验,分别得到准12、准6 mm棒材。结果表明,获得的产品组织均匀致密,晶粒细小,产品力学性能满足技术要求。TC4 alloy was compressed on Gleeble-1500 thermal simulator, and the deformation behavior was also analyzed under different temperatures and strain rates. It was ascertained that the optimal deformation beginning temperature was 950＂C, and the strain rate was 1 s1. Then by the self-manufactured eight Y-type mills, d^12mm and ~b6mrn rods were obtained respectively. The results show that microstructures both two size rods are fine and homogeneous. The mechanical properties of products meet technique requirements.
