Ultrahigh strength ductile microalloyed steel with a very low yield ratio developed by quenching and partitioning heat treatment [PDF]

open access: yesScientific Reports, 2022
In this study, a microalloyed low carbon steel was subjected to quenching and partitioning (Q&P) heat treatment processes. The primary ferrite-pearlite microstructure of the steel was transformed into a bainitic microstructure containing interlath and ...

Effect of solidification rate on microstructure evolution in dual phase microalloyed steel [PDF]

open access: yesSci Rep, 2016
In steels the dependence of ambient temperature microstructure and mechanical properties on solidification rate is not well reported. In this work we investigate the microstructure and hardness evolution for a low C low Mn NbTi-microalloyed steel ...

Control of the Austenite recrystallization in Niobium Microalloyed steels [PDF]

open access: yesMaterials Science Forum, 2009
The use of heavy gauge steel sheets for structural applications very often requires a combination of high yield strength and adequate toughness. The most cost effective way to realize a high yield strength and a high ductility in a low alloyed steel is ...

Hot deformation behavior of micro-alloyed steel using processing maps developed with different constitutive equations [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2022
The hot workability of microalloyed steel was studied in the deformation temperature range of 850–1200ºC and strain rate of 0.001-100s-1. The constitutive relation of flow stress with temperature, strain rate and strain was established to construct ...

Processes, microstructure and properties of vanadium microalloyed steels [PDF]

open access: yes, 2009
Vanadium as an important alloying element in steels was initially associated with the properties achieved following tempering. Interest in the microstructure was stimulated by the advent of transmission electron microscopes with a resolution of ~1nm ...

Development of Niobium Microalloyed Steel for Railway Wheel with Pearlitic Bainitic Microstructure [PDF]

open access: yesMaterials Research, 2020
Heavy haul transportation (load over 30 tons/axle), as well as the axle load, has been more and more used in Brazil and worldwide. The stress generated in the wheel-rail contact with loads up to 30 tons/axle is around 760 MPa, which causes premature wear
