Effects of heat input on the mechanical properties of butt-welded high and ultra-high strength steels
(Elsevier, 2019-08-09)
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 ...
Weldability of cold-formed high strength and ultra-high strength steels
(Elsevier, 2019-03-22)
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 ...
Use of the quasi-static Johnson-Cook model in the failure assessment of tensile specimens with metallurgical constraints
(Elsevier, 2020-04-10)
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 ...
Mechanical properties and microstructural evaluation of the heat-affected zone in ultra-high strength steels
(Elsevier, 2020-09-17)
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, 2022-09-09)
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 ...
