Structural and micromagnetic modeling of the magnetic binder phase in WC-Co cemented carbides

The magnetic properties of tungsten carbide with cobalt as a binder have long been used in industry to characterize the microstructure of this hard metal. We present bottom-up structural and micromagnetic modeling of WC-Co, from which we obtain coercive fields that compare well to experimental data. Future work will use experimentally obtained microstructure information as input to the structural modeling.
