ABSTRACT
14.1 Thermomechanical Treatment of Steel
Thermomechanical treatment (TMT) is a term used to describe various processes that combine controlled thermal and deformation treatments to obtain the following synergistic effects [1,2]:
Higher yield strengths
Improved toughness
Improved weldability
Higher resistance to brittle cleavage
Higher resistance to low-energy ductile fractures
Lower impact-transition temperature
Improved cold forming, particularly by bending
Lower costs by using hot-rolled instead of heat-treated sections.
