基于Murty判据的粗片层状TA15钛合金β相区锻造工艺参数优化
Optimization of Forging Processing Parameters in β Phase Field of Coarse Lamellar TA15 Titanium Alloy Based on Murty Criterion
摘 要
对粗片层状TA15钛合金在Thermecmaster-Z型热模拟试验机上进行等温恒应变速率压缩试验,采用基于Murty判据的加工图技术研究了该合金在温度1 000～1 100℃、应变速率0001～10 s-1参数范围内的微观变形机制,并优化出该合金的锻造工艺参数.结果表明:在β单相区变形时,TA15钛合金较佳的变形参数范围为1 030～1 075℃、0.001～0.03 s-1,以1 050℃、0.001 s-1附近为最佳,其变形机制为β晶粒充分均匀的动态再结晶;失稳区变形参数范围为1 000～1 100℃、1.78～10 s-1,在该区出现了β晶粒的不均匀变形.

Abstract
Hot compression tests of TA15 titanium alloy with coarse lamellar microstructure were conducted using Thermecmastor-Z hot working simulator.Microstructural deformation mechanisms were investigated by means of processing map technology based on Murty criterion in the temperature range of 1 000-1 100℃ and strain rate range of 0.001-10 s-1,and the forging thermal parameters were optimized.The results show that in β phase field the desired deformation regions were in the range of 1 030-1 075℃ and 0.001-0.03 s-1 with the deformation mechanism of full and uniform dynamic recrystallization,and the optimum deformation parameters were at 1 050℃ and 0.001 s-1.The regions of flow instability occurred in the temperature range of 1 000-1 100℃ and strain rate range of 1.78-10 s-1,and non-uniform deformation of β grains appeared in this range.
