摘要/Abstract

摘要： 采用倒置金相分析系统、透射电镜、软磁直流测量装置以及交直流软磁磁滞回线仪等研究了退火温度对含铜00Cr13Si2钢显微组织、力学性能和磁性能的影响。结果表明,随着退火温度的升高,试验钢的晶粒尺寸和析出相尺寸均增大,晶粒形貌由扁平状逐渐向近等轴状转变,小晶粒数量显著减少,而抗拉强度和铁损逐渐降低。同时,高温退火(850 ℃)下析出相由小于10 nm 粗化至约 20 nm,并在组织中呈不均匀分布。综合考虑,退火温度选择700 ℃时,该钢具有较好的力学性能和磁性能匹配,抗拉强度为591 MPa,屈服强度为463 MPa,磁感应强度B₂₅、B₅₀和B₁₀₀分别为1.34、1.43和1.53 T,在保证较高强度的同时获得最低的铁损和良好的磁滞特性。

Abstract: Effect of annealing temperatures on microstructure, mechanical properties and magnetic properties of 00Cr13Si2 steel bearing Cu was studied by using inverted metallographic analysis system, transmission electron microscope, soft magnetic DC measuring device, and AC and DC soft magnetic hysteresis loop instrument. The results show that with the increase of annealing temperature, the grain size and precipitated phase size of the steel increase, the grain morphology gradually transforms from flat to nearly equiaxed, and the number of small grains decreases significantly, while the tensile strength and iron loss gradually decrease. Meanwhile, the precipitated phases coarsen from less than 10 nm to about 20 nm under high temperature annealing (850 ℃), and distribute inhomogeneously in the microstructure. In comprehensive consideration, when the annealing temperature is 700 ℃, the steel has a good match between mechanical properties and magnetic properties, as the tensile strength is 591 MPa, the yield strength is 463 MPa, with the magnetic induction intensity B₂₅, B₅₀ and B₁₀₀ being 1.34, 1.43 and 1.53 T, respectively, indicating that the lowest iron loss and excellent hysteresis characteristics are obtained while ensuring high strength.
