摘要
SAE 1065 steel wire ropes are prone to individual wire fracture due to the martensite structure with high carbon and high microhardness formed on the wire surface because of friction. A new low-carbon microalloyed steel wire composed of lath bainite with fine carbides dispersed in bainitic ferrite and lath martensite is developed in this paper. For the developed steel wire with a diameter of 1.0 mm, the tensile strength and low-cycle fatigue resistance are higher than those of commercial SAE 1065 wire. It is shown that the individual wire fracture caused by as-quenched martensite formation and severe plastic deformation can be avoided in the developed steel wire. Also, the design process and associated manufacturing process are discussed in detail.
