Thermo-mechanical controlled processing (TMCP) for rolling has been developed to obtain high strength and toughness even at low temperature for plate, and there are many applications as real production. In case of forging, there were a few example applied TMCP. For automobile forged components, weight reduction is one of the most effective methods to reduce fuel consumption for decreasing the global warming. By the application of TMCP for forging process, named as controlled forging, the mechanical properties of forged components are extremely improved so that it can lead weight reduction.
