... cooling is increased . If the rate of cooling from high temperature is very high , there will be insufficient time for any diffusion of carbon within the y iron lattice to occur . While diffusion can be suppressed by a very rapid cooling ...

... cooled at a slower rate . This means that , while the surface layers may be converted into martensite , the rate of cooling at some little distance below the surface of the bar may be less than the critical cooling velocity of the steel ...
