摘要
PURPOSE: A method for producing Tb-Dy-Fe self deformation alloy composite is provided to produce Tb-Dy-Fe self deformation alloy composite with a good physical properties in a cost effective and simple manner by bulk treating a powder of Tb-Dy-Fe self deformation alloy by means of a polymer binder. CONSTITUTION: An ingot of Tb-Dy-Fe alloy is formed by a vacuum inductive melting or a vacuum arc melting. The ingot is pulverized into a powder. The powder is mixed with a polymer binder. The mixture is shaped and cured. The Tb-Dy-Fe alloy is composed of 10 atom% Tb, 23 atom% Dy and 67 atom% Fe. The binder is preferred to be selected from resins based on phenol, urea formaldehyde, melamine formaldehyde, polyester, epoxy and polyimide and have an amount ranging from 10 vol% to 40 vol% of the alloy powder. The powder has an average grain size between 11 and 160um. The shaping step is typically carried out by a press under a non magnetic field.
