The melting point also defines a condition ...

In the thermal sense, normalizing is an austenitizing heating cycle followed by cooling in still or slightly agitated air. Typically, the work is heated to a temperature about 55 °C (100 °F) above the upper critical line of the iron-iron carbide phase diagram. That is above Ac3 for hypoeutectoid steels and above Acm for hypereutectoid steels.

Tungsten carbide parts are typically comprised of a cemented carbide (or hardmetals), induvial WC grains imbedded in a metal binder matrix of either cobalt or nickel.
