Abstract

Phase stability of E21 (Co, Ni)3AlC was investigated from the viewpoint of magnetic properties in the Co-Ni-Al-C quaternary system. Isotherms of the Co-Al-C and Ni-Al-C ternary systems at 1373 K were revised and evaluated by means of electron probe microanalysis. Magnetic properties measurement revealed that discontinuity appearing on the chemical concentration dependence of Curie temperature and saturation magnetization of E21 (Co,Ni)3AlC indicates the existence of two types of E21 phase in the Co-Ni-Al-C quaternary system.
