Review on the prediction of residual stress in welded steel components [PDF]

open access: yes, 2020
Residual stress after welding has negative effects on the service life of welded steel components or structures. This work reviews three most commonly used methods for predicting residual stress, namely, empirical, semi-empirical and process simulation ...

Effect of Ni addition on bainite microstructure of low-carbon special bar quality steels and its influence on CCT diagrams

open access: yesJournal of Materials Research and Technology, 2021
This work presents the effect of Ni content on the bainite morphology and in the mechanical properties of low-carbon special bar quality steels. Four steel ingots with the same base chemical composition, having only Ni content as their main difference ...

Continuous Cooling Transformation Diagrams of 2.25Cr-1Mo-0.25V Submerged-Arc Weld Metal and Base Metal

open access: yesMetals, 2020
The transformation behavior and microstructural evolution during continuous cooling within the heat affected zone between the weld beads of a 2.25Cr-1Mo-0.25V all-weld metal and the corresponding 2.25Cr-1Mo-0.25V base metal were investigated by means of ...

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]

open access: yes, 2016
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.

Towards the ab initio based theory of the phase transformations in iron and steel [PDF]

open access: yes, 2017
Despite of the appearance of numerous new materials, the iron based alloys and steels continue to play an essential role in modern technology. The properties of a steel are determined by its structural state (ferrite, cementite, pearlite, bainite ...

Bainite kinetic transformation of austempered AISI 6150 steel

open access: yesJournal of Materials Research and Technology, 2020
This research studies the kinetic transformation and austempering temperature effect on the morphologies of bainite for AISI 6150 steel. A minimum of 10 different holding times for each austempering temperature were utilized.
