摘要
通过大量实验从贝氏体形成和强韧化理论上分析了非调质抽油杆用钢疲劳断裂的原因。
The cause of fatigue break of steel without modification used for sucker rod is analysed from theories of bainite deformation and strong malleablizing on the basis of a quantity of tests,the optimized cooling process to guarantee the quality of this kind of steel after forged have been worked out.
