Metal Science and Heat Treatment Aims and scope

Methods of super fast hardening of liquid metal in the production of noncrystalline magnets based on Fe – Nd – B are studied. The effect of the rate of cooling in crystallization of alloys Fe – 34% Nd – 1.3% B – 0.5% Ti and Fe – 32% Nd – 1.3%B–2%Dy– 0.5% Ti on the magnetic properties of sintered magnets produced from them is determined. It is shown that the cast alloys should be subjected to accelerated cooling.
