The Effect of Niobium in the Heat-affected Zone of Microalloyed Steel
… of thermomechanically processed Nb microalloyed linepipe steels is destroyed in the vicinity of welds used in fabricating pipelines. There are conflicting views on the influence of niobium in the `heat-affected zone', particularly in the region closest to the weld fusion line which …

Multiphase particle-size-grouping model of precipitation and its application to thermal processing of microalloyed steel
… alloy composition and temperature history. In microalloyed steel, for example, precipitates may lead to beneficial grain refinement or detrimental transverse surface cracks. A comprehensive set of models has been developed to determine precipitate formation during metal processing. They include …

Effect of equalisation time and temperatures on microstructures of simulated directly and conventionally charged V - microalloyed steels
… and 1333 min) were applied to three V- and V-Ti- microalloyed steels, which contain a low carbon content (0.067 ~ 0.073 wt%) and high nitrogen content (0.017 ~ 0.021 wt%), by the simulated direct charging or conventional cold charging processes. The experimental results show that in directly …

Assessment of the microstructure and torsional fatigue performance of an induction hardened vanadium microalloyed medium-carbon steel
Vanadium microalloying of medium-carbon bar steels is a common practice in industry for a number of hot rolled as well as forged and controlled-cooled components. However, use of vanadium microalloyed steels has expanded into applications beyond their originally designed controlled-cooled …

Low Temperature Cleavage Fracture of Microalloyed Bainitic Plate Steels
… was investigated using four experimental microalloyed bainitic plate steels. The four plate samples were produced by different thermomechanical processing (TMP) schedules and had yield strengths in the range 540 - 670 MPa. Microstructures were characterized by optical microscopy (OM), …
