Effects of heat input on the mechanical properties of butt-welded high and ultra-high strength steels
(Elsevier, 09.08.2019)In this study, the mechanical properties of butt-welded thin plates made of S700, S960 and S1100 steels under various heat inputs (HI) are investigated. The gas metal arc welding (GMAW) process with two different levels ... -
Finite element simulation of welding distortions in ultra-high strength steel S960 MC including comprehensive thermal and solid-state phase transformation models
(Elsevier, 17.06.2020)The objective of this study is developing a thermo-metallurgical-mechanical finite element (FE) model incorporating the effect of solid-state phase transformation (SSPT) to accurately simulate deformations for single ... -
Mechanical properties and microstructural evaluation of the heat-affected zone in ultra-high strength steels
(Elsevier, 17.09.2020)This paper presents an investigation into the mechanical properties of ultra-high strength steels (UHSSs) (with nominal yield stress of 960 and 1100 MPa) after welding. Seven weld thermal cycles were simulated using a ... -
Mechanical properties of butt-welded ultra-high strength steels at elevated temperatures
(Elsevier, 09.09.2022)Variety of ultra-high strength steels (UHSS) with different microstructural characteristics is becoming available with continuous development of the manufacturing process in the steel industries. In order to effectively ... -
Use of the quasi-static Johnson-Cook model in the failure assessment of tensile specimens with metallurgical constraints
(Elsevier, 10.04.2020)Direct quenching has recently been used to develop cost-effective novel high and ultra-high strength steels. In weldments made of these steels, a distinct soft zone, which can lower the ultimate strength and deformation ... -
Weldability of cold-formed high strength and ultra-high strength steels
(Elsevier, 22.03.2019)Hollow sections and cold-formed steels have a key role in modern structures and machinery. In addition, to benefit from full potentials of cold-formed steels, it is usually required to weld them to other steel parts of ...
