Heat Treatment Processes Hardening. Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
Wood is air-dried or dried in a purpose built oven (kiln). Usually the wood is sawed before drying, but sometimes the log is dried whole. Case hardening describes lumber or timber that has been dried too rapidly.Wood initially dries from the shell (surface), shrinking the shell and putting the core under compression.When this shell is at a low moisture content it will 'set' and resist shrinkage.ase hardening describes lumber or timber that has been dried too rapidly.
