摘　　要：研究了cf53钢的静弯性能、弯曲疲劳性能。用小能量多冲试验测出了cf53钢的A－N曲线，分析了不同能量下多冲断口的微观断裂机制。A study was made of the dead bending property of steel cf53. The A-N curve of its high frequency induction hardening was measured by the method of repeated impact test. A new formula for prediction of the repeated impact fatigue crack initiation life from the tensile properties of steel cf53 has been developed. Micromechanism of repeated impact fracture in different conditions has been analysed with SEM

关 键 词：弯曲疲劳 冲击试验 调质钢
