Oct 01, 2008 Heat Treatment: Heat treatment is any method of applying heat to a metal. The source of heat can be gas, oxy-acetylene, electricity micro-wave, laser, etc. There are always three aspects to the heat treatment cycle: (1) heat up to the selected temperature, (2) soak at that temperature and (3) cool down from that temperature.

Jul 18, 2002 With high carbon/chrome alloys, especially as-cast there can be a good deal of primary carbides and segregation of them. To get high hardness the carbon needs to get get into solution in the austenite during the soak heat treatment. This will happen as temperature is raised or when time at temperature is increased.
