摘要： Disclosed in the present invention is a nanocrystalline soft magnetic alloy with high magnetic induction and high frequency. The nanocrystalline soft magnetic alloy has a molecular formula of FeaSibBcMadCuePf, in which M includes one or more of Nb, Mo, V, Mn, and Cr, molar percent contents of elements are as follows: 6≤b≤15, 5≤c≤12, 0.5≤d≤3, 0.5≤e≤1.5, and 0.5≤f≤3, and the balance includes Fe and impurities. A difference between an induced anisotropy value and an average magnetocrystalline anisotropy value is 0.1-1 J/m3. The soft magnetic alloy has high magnetic permeability and low magnetic loss at high frequency. Further disclosed in the present disclosure is a method for preparing the nanocrystalline soft magnetic alloy with high magnetic induction and high frequency. Based on a repeated cycle of a thermal field, a transverse magnetic field, and a cold field, the induced anisotropy value (Ku) is similar to the average magnetocrystalline anisotropy value ( ), so that soft magnetic properties at high frequency are improved.

摘要： In the method of producing a martensitic stainless steel strip, a quenching furnace of a quenching process includes at least a temperature raising unit and a holding unit. When a predetermined quenching temperature is set as T (° C.), the temperature raising unit is set to be within a temperature range of 0.7T (° C.) or higher and lower than T (° C.), and a set heating temperature on an exit side of the steel strip is set to be higher than a set heating temperature on an entry side of the steel strip when the steel strip passes through the temperature raising unit. The holding unit is set to the quenching temperature T (° C.). A time spent in the furnace by the steel strip in the temperature raising unit is equal to or longer than a time spent in the furnace by the steel strip in the holding unit.
