WebOct 11, 2024 · • TTT diagram denotes that it is drawn at different cooling rates, hence it is not recorded as an equilibrium diagram as Iron carbide diagram. 15. HEAT TREATMENT • An operation or combination of … WebPure iron, wrought iron, and extremely low-carbon steels have very little hardening properties and are dif-ficult to harden by heat treatment. Cast iron has limited capabilities for hardening. When you cool cast iron rapidly, it forms white iron, which is hard and brittle. In plain carbon steel, the maximum hardness ob-tained by heat treatment ...
