采用Gleeble-3800型热模拟试验机研究了变形参数对Haynes 282合金热变形时流动应力的影响规律，建立了Haynes 282合金高温塑性变形时的热加工图。结果表明：在达到峰值应变后，当变形温度在1000℃及以下时，合金的软化速率一直大于硬化速率，应力持续下降；当变形温度大于1000℃时，加工硬化速率和再结晶软化速率达到动态平衡。合金热加工图包含两个危险区，危险区I:温度900～1000℃、应变速率0.1～10 s-1和危险区Ⅱ:温度1000～1200℃、应变速率1～10 s-1;热加工图中失稳区是由温度900～1000℃、应变速率0.1～10 s-1和温度1000～1150℃、应变速率0.1～1 s-1组成的区域；安全区对应的温度范围为1000～1200℃,应变速率为0.01～0.1 s-1,该区的功率耗散系数为0.34～0.44,是合适的热加工区。
Abstract：Effect of deformation parameters on flow stress of Haynes 282 alloy during hot deformation was studied by Gleeble-3800 thermal simulation testing machine, and the hot processing map of the Haynes 282 alloy during high temperature plastic deformation was established. The results show that after reaching the peak strain, when the deformation temperature is 1000 ℃ and below, the softening rate of the alloy is always greater than the hardening rate, and the stress decreases continuously; when the deformation temperature is greater than 1000 ℃, the work hardening rate and recrystallization softening rate reach dynamic balance. The hot processing map of the alloy includes two danger zones: danger zone I: temperature of 900-1000 ℃, strain rate of 0.1-10 s-1 and danger zone II: temperature of 1000-1200 ℃, strain rate of 1-10 s-1. The instability zone in the hot working diagram is composed of temperature of 900-1000 ℃, strain rate of 0.1-10 s-1 and temperature of 1000-1150 ℃, strain rate of 0.1-1 s-1. For the safety zone, the corresponding temperature range is 1000-1200 ℃, the strain rate is 0.01-0.1 s-1, and the power dissipation coefficient is 0.34-0.44, which is a suitable hot processing zone.
