Problems solved by technology

[0005] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a high-strength 1J22 strip and its manufacturing method. The high-strength 1J22 strip adds Nb and Cr to the original composition, and through a special treatment process, it can significantly improve The mechanical properties of the 1J22 strip are improved, so that the high-strength 1J22 alloy can meet the coercive force Hc≤110A / m, the tensile strength Rm>590MPa, and the yield strength ReL>360Mpa. The production method of the 1J22 strip involves rapid cooling , ice salt water quenching and other technical points, which solve the technical problems that the existing iron-cobalt alloy 1J22 strip has high magnetic properties after heat treatment, but poor mechanical properties and low product life

Abstract

The invention discloses a high-strength 1J22 strip and a manufacturing method thereof and belongs to the field of alloy material machining and processing. According to the high-strength 1J22 strip, Nband Cr are added to original components, mechanical properties of the 1J22 strip are promoted significantly with a special processing technology, thus the high-strength 1J22 alloy can meet the requirements that coercive force Hc is smaller than or equal to 110 A / m, tensile strength Rm is larger than 590 MPa, and the yield strength ReL is larger than 360 MPa. The manufacturing method of the 1J22 strip relates to fast cooling, brine ice quenching and other technical points, and the technical problems that after heat treatment is conducted on an existing ferrocobalt 1J22 strip, the material is high in magnetic performance, but mechanical property strength is poor, and product life is short are solved.

Description

technical field [0001] The invention belongs to the field of alloy material processing, and in particular relates to a high-strength 1J22 strip and a manufacturing method thereof. Background technique [0002] Soft magnetic alloy is an important metal soft magnetic material, which has good magnetic properties, its Curie temperature is as high as 980 °C, the saturation magnetic induction at room temperature is as high as 2.4T, and it has high magnetic permeability and low coercive force. Soft magnetic alloys are mainly used in transformers and motors, as well as in the production of diaphragms for telephones, high-speed printers and receiver coils. At the same time, compared with other materials, this alloy can significantly reduce the weight and volume, and has an irreplaceable application status in the fields of aviation and aerospace. The most important application is to make the core component of the aero-generator - the rotor and stator. [0003] However, the mechanica...
