High-Coercivity Decomposition in Fe-(15, 23)%Co-30%Cr-3%Mo-0.5%Ti Alloys

摘要

The dependences of the magnetic properties of Fe-(15,23)%Co-30%Cr-3%Mo-0.5% Ti alloys on the temperatures of isothermal thermomagnetic treatment and the second stage of two-stage magnetic annealing and the results of thermomagnetic analysis of these alloys demonstrate that the sequence of high-coercivity decomposition in them differs from that in alloys with lower contents of chromium, molybdenum, and titanium. The decomposition in the Fe-(15, 23)%Co-30%Cr-3%Mo-0.5% Ti alloys is similar to that in Alnico-type (YuNDKT) alloys with high cobalt (38-42%) and titanium (8%) contents.
