Embodiment Construction

[0068] The specific implementation, composition, features and effects provided by the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0069] see Figure 2-3 , a Fe-23Cr-15Co-Mo-Ti permanent magnetic alloy Fe-23Cr-15Co-Mo-Ti compounded with molybdenum and titanium elements, its weight percentage composition is: chromium (Cr) 23-27%, cobalt (Co) 10-16%, molybdenum (Mo) 1%-3%, titanium (Ti) 0.5%-1.0%, the rest is iron and unavoidable impurities;

[0070] The preferred composition weight percentage is: 23.05% of chromium (Cr), 15.21% of cobalt (Co), 2.89% of molybdenum (Mo), 0.53% of titanium (Ti), and the rest are iron and unavoidable impurities;

[0071] Since the main component of Fe-23Cr-15Co alloy is iron (Fe), appropriate addition of body-centered cubic structural elements molybdenum and titanium can expand the α-phase region of iron and make the α-phase more stable, thereby effectively reducing th...

Abstract

The invention discloses a permanent magnet alloy of Fe, Cr and Co with composite molybdenum and titanium and a deforming and processing technique thereof, belongs to the field of permanent magnet alloy materials of Fe, Cr and Co, and particularly relates to the alloy of Fe, Cr and Co that has reduced Co content and improved processing performance and the deforming and processing method thereof. The permanent magnet alloy of Fe, Cr and Co with composite molybdenum and titanium consists of following ingredients by weight: 23 to 27 percent of chromium (Cr), 10 to 16 percent of cobalt (Co), 1 to 3 percent of molybdenum (Mo), 0.5 to 1.0 percent of titanium (Ti) and residual quantity of ferrum and unavoidable impurities. The invention can effectively reduce Co content, lower material cost, and improve the magnetic performance and the mechanical processing performance of the alloy material; the processing technique that is provided by the invention comprises a smelting procedure, a smithing procedure, a hot rolling procedure, an acid cleaning procedure, a cold processing procedure and a magnetic performance processing procedure, each of which is arranged reasonably, thus further obtaining higher magnetic performance of the alloy and providing a better method for the deforming and processing of the permanent magnet alloy material of Fe, Cr and Co with high magnetic performance.

Description

technical field [0001] This case belongs to the field of iron-chromium-cobalt permanent magnetic alloy materials, and in particular involves iron-chromium-cobalt alloys with reduced cobalt content and improved processing performance and their deformation processing methods. Background technique [0002] With the development of product diversification in the electromechanical industry and information industry, deformation processing of high-performance magnetic materials is an urgent problem to be solved. [0003] The permanent magnetic alloy materials widely used in the market mainly include cast AlNiCo, ferrite, rare earth, and NdFeB. These materials are produced by casting or powder metallurgy. Although they have high magnetic properties, they have poor mechanical properties and are not feasible Machinability, with various defects of casting or powder metallurgy, cannot manufacture slender, thin, complex-shaped, and dimensionally accurate permanent magnet components.
