摘要： 在Gleeble-1500热模拟机上进行了低合金钢12Cr1MoV热模拟实验,测试了从600℃到峰值温度,涵盖了连铸时从结晶器到输出辊道的整个温度范围,得出了12Cr1MoV在不同应变速率不同温度下的流变曲线、强度曲线和热塑性曲线,观察了不同温度下试样的断口形貌组织.实验结果表明:低合金钢12Cr1MoV的ZST为1425℃,ZDT为1400℃.在1100~1300℃范围内,钢的断面收缩率均大于60%,具有良好的塑性;脆性范围为1350℃到熔点和900℃以下.

Abstract: The high-temperature mechanical properties of the low-alloy steel 12Cr1MoV during continuous casting were tested on a Gleeble-1500 thermal simulator within the temperature range from mold to outlet rollers. As a result, the plastic flow and strength and thermal plasticity curves at different strain rates from 600°C to peak temperature were given, with fracture morphology of specimens observed at different temperature. The test results showed that the ZST and ZDT of the steel are 1425°C and 1400°C, respectively. The percentage reduction of area of the tested steel is greater than 60% within the range from 1100°C to 1300°C, thus showing that the steel has higher resistance to high-temperature cracking. Its brittle temperature range is 1350°C to melting point and below 900°C.
