摘要： 采用Gleeble 1500热模拟试验机研究了0.008 7%～0.150 0%N对热轧0Cr18Ni9N钢(%:0.044～0.049C、0.41～0.51Si、1.46～1.52Mn、17.92～18.15Cr、9.09～9.24Ni、0.01～0.03Ti)以应变速率5×10-3s-1和1s-1在800～1300℃的拉伸和压缩性能的影响,并分析了N含量对该钢动态再结晶性能的影响。结果表明,随着N含量的增加,该钢断面收缩率显著下降,同时其最佳热塑性的温度区间提高;当N含量低于0.0500%时,最佳热塑性区间为950～1100℃;而当N含量为0.0800%～0.1500%时,则为1150～1250℃。

Abstract: The effect of 0. 008 7% 〜0. 150 0% N on tensile and compression properties of hot-rolled steel 0Crl8Ni9N (% ： 0.044 〜0.049C, 0.41 〜0.51Si, 1.46 ~ 1.52Mn, 17. 92 ~ 18. 15Cr, 9.09 〜9.24Ni, 0.01 〜0.03Ti) with strain rate 5 x 10-3s-1 and 1 s-1 at 800 〜130 0 °C has been studied by using Gleeble 1500 thermal simulation machine and the effect of N content on dynamic recrystallization of the steel is analyzed. Results show that with increasing N content in steel the reduction of area of the steel obviously decreases while its optimum temperature range of thermoplasticity increases ； as the N content in steel is less than 0. 050 0% , the optimum temperature range of thermoplasticity of the steel is 950 - 110 0  °C, and as N content is 0.080 0% 〜0. 150 0% , that is 1150 - 1250 °C .
