Thermomechanical Treatments of Ultrahigh Carbon Steels

Thermomechanical processing allows the attainment of spheroidized microstructures that show improved mechanical properties.In this work,a thermomechanical processing route consisting of two steps was developed for two ultrahigh carbon steels (UHCS) containing 1.3 and 1.5%C.This route develops structures of fine spheroidized cementite particles in a fine-grained ferrite matrix.Thermomechanical Steel Processing and HAZ Properties - TWIThese TMCP steels generally offer good weldability,particularly a high resistance to hydrogen cracking and superior heat affected zone toughness relative to conventional processing methods,and can also exhibit superior sour service properties.Thermomechanical Processing of High-Strength Low-Alloy Oct 22,2013 Thermomechanical Steel Processing and HAZ Properties#0183;Thermomechanical Processing of High-Strength Low-Alloy Steels considers some advanced techniques and metallurgical bases for controlled-rolling.This book contains 12 chapters.In Chapter 1,the purpose of thermomechanical processing and historical survey is described,while in Chapter 2,the kinetics of phase transformations and refinement of

The Role of Vanadium in Microalloyed Steels Vanitec

The different behaviours of these elements in steel processing are shown to depend on the varying solubilities of their carbonitrides in austenite.The relatively high solubility of V(C,N) in austenite means that vanadium plays only a minor role during hot deformation and mostly remains available for precipitation strengthening during Texture and mechanical properties of API X100 steel Jan 01,2012 Thermomechanical Steel Processing and HAZ Properties#0183;The microstructure of base,heat affected zone (HAZ),and weld metal of the fabricated steel pipe was examined by optical and transmission electron microscopy.The microstructure of thermomechanically processed pipeline steel primarily consisted of non-equiaxed ferrite of mixed morphologies with small fraction of degenerated pearlite.Texture and mechanical properties of API X100 steel Jan 01,2012 Thermomechanical Steel Processing and HAZ Properties#0183;Abstract The mechanical properties of steels are strongly influenced by microstructure and texture developed during thermomechanical processing.Here,different annealing treatments have been performed on pipeline steel at inter-critical temperatures.
