Obtaining high levels of mechanical properties in steels is directly linked to the use special forming processes and addition alloying elements during their manufacture. This work presents a study hot-rolled steel strip produced achieve yield strength above 600 MPa, using niobium microalloyed HSLA with non-stoichiometric titanium (titanium/nitrogen ratio 3.42), rolled on Steckel mill. A major c...

Abstract A good selection of the thermomechanical processing parameters will optimize function alloying elements to get most mechanical properties in Advanced High-Strength Steels for automotive components, where high resistance is required passenger safety. As such, critical temperatures must be defined taking into account alloy composition, order effective schedules designed. These mainly inc...

Impurity elements of Cu, Ni, Sn and Cr have been added to a model low-carbon strip steel mimic the levels that could arise due increased scrap recycling during production. The microstructure tensile properties base composition impurity compositions after thermomechanical processing, consisting hot rolling simulated coil cooling, investigated. addition impurities results in lower bainite fractio...

Purpose: To provide a preliminary evaluation of health outcomes for a type of thermomechanical massage device used in Asia, Middle East, and Europe and now in the United States. The device under study is manufactured by Migun Medical Instruments International (Taejeon, Korea) and has an estimated usage of 24-35 million client-sessions per year worldwide. Methods: findings were obtained from unp...
