水文报导了对川种符合APl-杯准的最低屈服限为450～520牛顿/毫米~2的调质或热机械加工状态的细晶粒结构钢在20～60℃温度之间进行的Battelle落锤试验。试验采用的试样具有符合API-标准的缺口、缺口堆焊层以及疲劳裂纹。根据载荷——挠度曲线测得裂纹发生及扩展所消耗的落锤能。比较了所消耗能量比份与前切断口比份随温度而变化的曲线。该项试验采用能量测定法是合理的。获得了落锤试验中测定硬化倾向较小的高韧性钢转变温度的适宜的测试条件。
Hydrology reports that Battelle falls between 20 and 60 ° C for fine grained structural steels of the type that meet the AP1-cup criteria for tempering or thermomechanical processing with a minimum yield of 450 to 520 N / mm2 Hammer test. The test specimens used have API-standard notches, notched build-up and fatigue cracks. According to the load - deflection curve measured crack occurrence and expansion of the consumed drop energy. The curves of the ratio of the energy consumed and the ratio of the front cut to the temperature are compared. The test using energy is reasonable. The suitable test conditions for determining the transition temperature of high ductility steels with less tendency to harden in the drop-weight test were obtained.
