| 英文摘要 | Cracking resistance is vital to the practical application of spring steels, which consists of fracture toughness (KIC) under the quasistatic loading condition and fatigue crack propagation (FCP) resistance under the cyclic loading condition. In the present study, the relation between the KIC/FCP resistance and microstructure of the 50CrMnSiVNb spring steel tempered at various temperatures is studied. In the results, it is shown that the dislocation density is the main factor influencing the KIC and FCP resistances, and the carbide size/quantity and morphology can also affect the KIC and FCP resistances. Thus, reducing the dislocation density is the most effective method to enhance the cracking resistance of the investigated steel. Moreover, decreasing the aspect ratio and obtaining a moderate size of tempered carbides are also beneficial to the cracking resistance. In addition, free hydrogen atoms can cause intergranular fracture on the fracture surface, worsening the FCP rate. To enhance the FCP resistance, smelting processes need to be improved to reduce the hydrogen content of the investigated steel. Herein, the relation between the KIC/fatigue crack propagation (FCP) resistance and microstructures of the 50CrMnSiVNb steel tempered at various temperatures is studied. The dislocation density is the main factor influencing the KIC and FCP resistances, and the carbide size/quantity and morphology are the secondary factor.Reducing the dislocation density is the most effective method to enhance the cracking resistance.image (c) 2024 WILEY-VCH GmbH |
