Study of the Thermomechanical Treatment Post-Deformation Maintaining Time Influence on the Mechanical Characteristics of the Microalloyed Steels
MetadataShow full item record
This paper-work shows the results of the laboratory researches of the postdeformation maintaining time influence on the physical-mechanical characteristics of the flat microalloyed steels, at high temperature thermomechanical treatments. The experiments have been made on the equipments of the Plastic Deformation and Thermal Treatments Laboratory from Faculty of Metallurgy and Materials Science using X60 steel – grade test specimen made at Mittal Steel Galati. The results of the laboratory experiments illustrated the importance of this technological parameter, which, together with temperature and deformation degree, decisively influences the structure and mechanical characteristics with a certain chemical composition of steel.
