摘要

试验用1Cr17Mn6Ni5N钢(/%:0.09~0.11C

0.19~0.29Si

7.33~7.42Mn

0.011~0.015P

0.004~0.007S

16.87~17.24Cr

5.06~5.19Ni

0.21~0.40N)由10kg真空感应炉熔炼

通过氮气气氛加氮化铬进行N合金化。通过Gleeble-1500D热模拟试验机将实验钢在真空下1150~1 000℃

以应变速率10

进行压缩60%试验。结果表明

在高温下

以低应变速率压缩时钢的动态再结晶是主要的软化机制;以高应变速率压缩时钢的动态回复是主要的软化机制;与0.21%N和0.29%N试验钢相比

含0.40%N的试验钢具有较高的峰值应力

根据Zener-Hollomon参数的计算得出0.40%N的试验钢再结晶激活能最高

在高温下不易发生动态再结晶。

Abstract

The test steel 1Cr17Mn6Ni5N (/% ： 0. 09 ~ 0.11C

0.19 ~ 0.29Si

7.33~7.42Mn

0.011 -0.015P

0. 004 ~ 0. 007S

16. 87 ~ 17. 24Cr

5. 06 ~5.19Ni

0. 21 ~0. 40N) is melted by a 10 kg vacuum induction furnace with adding chromium nitride to N-alloying in nitrogen atmosphere. The compression 60% experiment of test steel in vacuum with strain rate 10

and 1 s

at 1 150 ~ 1 000 ℃ has been carried out by using Gleebl-1500D thermo-mechanical simulation machine. Test results show that at high temperature with lower strain rate the dynamic recrystallization of steel is main softening mechanism and with higher strain rate the dynamic recovery of steel is the main softening mechanism as compared with 0. 21

% N and 0.29% N test steels the 0. 40% N test steel has higher peak stress

and based on the calculation of Zener-Hollomon parameter

the recrystallization activation energy of 0. 40% N test steel is highest

uneasily to happen dynamic crystallization at elevated temperature.
