| 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℃。

| Abstract: | 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(e)0~0.8,strain rate 1～2.5s-1 at 1030~ 1300 ℃ and the effect of temperature on max stress and reduction of area of alloys have been studied by using Thermomac-master-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 1100~1240 ℃ for alloy G3,1130～1220 ℃ for alloy G3-Z and 1050~1240 ℃ for alloy 825. |
