摘要 采用系列冲击试验和动态撕裂试验研究了屈服强度大于550MPa、含铜量为1%的热轧低合金钢板(板厚为6mm)的韧脆转变行为。结果表明,该钢具有很低的韧脆转变温度,ETT50和FATT50均低于-100℃。 The ductile brittle transition behaviour of hot-rolled steel containing copper about 1% is investigated through charpy notch impact test and dynamic tear test. The yield strength of the steel is over than 550MPa. The result indicates that the temperature of the transition from ductile to brittle is very low. ETT50 and FATT50 are below - 100℃.
