Grain Refinement in Bulk Undercooled Fe-Co Base Alloys
In this work,applying fluxing purification and cycling superheating method,Fe44Co44Nb7B4Cu1 melts were undercooled and microstructure evolutions of the two different kinds of Fe44Co44Nb7B4Cu1 alloy samples prepated by undercooling solidification and copper mould chilling were studied.
