Abstract
The thermomagnetic analysis of the intermetallic phases in the mischmetal-cobalt (MM-Co) system was used to (1) establish the identity of the structurally similar 1 : 3, 2 : 7, 5 : 19, and 1 : 5 phases by means of their distinctive Curie temperatures (< 20, 61, 270, and 541 ° C, respectively), (2) indicate a new magnetic transition at 340 ° C between the Tc of 5 : 19 and 1 : 5 phases, (3) provide unambiguous evidence for 5 : 19 and 2 : 17 phases as decomposition products of the in situ eutectoid decomposition of 1 : 5 phase, (4) confirm the existence of a homogeneity region of 1 : 5 phase with Tc varying from 487 to 520 ° C with increasing Co, and (5) demonstrate the enhancement of Tc of 1 : 5 when Co replaces Fe.
