摘要

通过Gleeble-1500D热模拟试验机对0～0.034%Ce的超级双相不锈钢00Cr25Ni7Mo4N(%:0.016～0.020C、24.50～24.72Cr、7.06～7.18Ni、3.61～3.73Mo、0.26～0.27N)进行了950～1 200℃、应变速率5×10

的热压缩试验。结果表明

适量铈的加入能提高00Cr25Ni7Mo4N钢的热塑性

铈含量为0.012%时有最好的热塑性;铈含量为0.021%以上时

该钢的峰值应力低于未加稀土钢;铈的加入有助于钢提前达到稳态流变阶段。

0.26~0.27N) at 950~1200℃ have been carried out by using Gleeble- 1500D thermal simulation machine. Results show that adding suitable cerium is available to increase the hot plasticity of steel 00Cr25Ni7Mo4N

and the steel containing 0.012Ce% has optimum hot plasticity; as the Ce content is more than 0.021%

the peak stress of the steel is lower than that of steel non-adding rare earth elements; and adding Ce is available to reach steady state deformation stage in advance.
