摘要
采用V型缺口试样,通过系列温度的冲击试验,以冲击吸收功、纤维断面率的变化对4130X钢的韧脆转变温度进行了测定。试验结果表明,4130X钢韧脆转变温度为-40℃。
In this research, based on Charpy V-notch impact tests at different temperature, the impact absorbing energy and percentage of ductile fracture surface was discussed to determine the ductile-brittle transition temperature for 4130X steel. The test result was showed that the ductile-brittle transition temperature for 4130X steel is -40℃.
