Abstract

In the present work, solid-state reactions in Sm-2(Co, Fe, Cu, Zr)(17)-type alloys have been investigated by means of in situ electrical resistivity measurements. Changes in the electrical resistivity of a Sm(Co0.74Fe0.1Cu0.12Zr0.04)(8.5) alloy after solid solution treatment at 1190 degrees C, quenching to room temperature, and during isothermal ageing at temperatures between 400 and 900 degrees C, have indicated microstructural/phase changes occurring at temperatures below those commonly used for the development of high coercivity in Sm(Co, Fe, Cu, Zr)(z)-type materials. Subsequent crystallographic and magnetic transition measurements have shown a high degree of correlation with respect to the changes observed in the electrical resistivity during isothermal ageing.
