通过系列温度冲击试验,采用V、U型缺口的试样,以冲击吸收功、纤维断面率结合断口微观形貌的变化对35CrNi3MoV钢的韧脆转变温度进行测定分析.试验表明:35CrNi3MoV钢韧脆转变温度为-60℃.
The ductile-brittle transition temperatures of 35CrNi3MoV steel were measured and analyzed by means of a series of temperature impact tests and V / U-notch specimens with impact absorbed energy and fiber cross-sectional area combined with the changes of fracture surface morphology. The transition temperature is -60 ℃.
