Abstract
A method for manufacturing a sintered compact includes the steps of preparing an alloy powder having a composition represented by Expression 1: RT(where, R is at least one kind of rare earth metal, T is at least one kind of transition metal, and w defines a relation of 1<w<4), sintering the alloy powder in a vacuum atmosphere or an atmosphere containing gas with a molecular weight of 30 or less, and processing the alloy powder by a hot isostatic pressing. The sintered compact has a high density, and reduces deteriorations in its sintered compact properties such as magnetostrictive properties in an air atmosphere at high-temperatures.
