Weldability of cold-formed high strength and ultra-high strength steels
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 ...
Mechanical properties and microstructural evaluation of the heat-affected zone in ultra-high strength steels
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 ...
