摘要
用Thermomacmaster-Z热模拟机和TEM,SEM研究了G3(%:0.012C、46.51Ni、24.71Cr、8.88Mo、1.15W、1.72Cu、0.10Nb)、G3-Z(%:0.014C、46.53Ni、24.05Cr、6.89Mo、1.09W、1.70Cu)和825耐蚀合金(%:0.006C、43.77Ni、22.10Cr、3.24Mo、1.90Cu、0.86Ti)1 030～1 300℃、应变量(ε)0～0.8、应变速率1～2.5 s^(-1)的应力-应变曲线和温度对合金最大应力和断面收缩率的影响,并分析了合金发生动态再结晶的影响因素。结果表明,G3、G3-Z、825合金动态再结晶的晶粒大小随温度补偿系数Z的增大而减小;G3、G3-Z、825合金适宜的热加工温度范围分别为1 100～1 240℃、1 130～1 220℃和1 050～1 240℃。
The stress-strain curves of corrosion resistant alloys G3 （%： 0. 012C, 46. 51Ni, 24.71Cr, 8.88Mo, 1.15W, 1.72Cu, 0. 10Nb）, G3-Z （% ： 0. 014C, 46. 53Ni, 24. 05Cr, 6. 89Mo, 1.09W, 1.70Cu） and alloy 825 （% ： 0. 006C, 43.77Ni, 22. 10Cr, 3.24Mo, 1.90Cu, 0. 86Ti） with strain （ε） 0 - 0. 8, strain rate 1 - 2. 5 s-1 at 1 030 - 1 300℃ and the effect of temperature on max stress and reduction of area of alloys have been studied by using Thermomaemaster-Z hot simulator, TEM and SEM, and the effect factors on dynamic recrystallization of alloys were analyzed. Results showed that with increasing temperature compensating factor Z, the grain size of dynamic-crystallizing of alloy G3, G3-Z and 825 decreased, and the available temperature range for hot-working was 1 100 - 1 240 ℃ for alloy G3, 1 130 - 1 220 ℃ for alloy G3-Z and 1 050 - 1 240 ℃ for alloy 825.
