Cobalt Iron Vanadium (Co-Fe-V (49/49/2 wt%))-Aggregate/Lump

Cobalt Iron Vanadium (Co-Fe-V (49/49/2 wt%))-Aggregate/Lump introduce:

Characteristic




Iron-cobalt-vanadium alloy refers to the Fe - Co - V permanent mag-netie alloy, which contains 52% cobalt, 9% - 23% vanadium, and the rest is iron.




The alloy is y - phase austenite with face - centered cubic at high temperature.With the increase of vanadium content, the lower phase of quenching residue in the alloy increased and presented a two-phase state (a+y) at room temperature.After cold processing with a deformation of more than 80%, almost all the 7 phases were transformed into a phase.Finally, after tempering near 600 'C, the uniformly dispersed lower phase was precipitated from the a phase, resulting in coercivity H.Significantly increased.
