Prospect of High-performance Welded Steel Bridge

The development of several grades of high-performance steel (HPS) with yield strengths of the order of 480 to 690 MPa (even more) with improved weldability, toughness and corrosion resistance have changed the scenario of fabrication of welded steel bridges for highway and rail bridge constructions. The HPS possesses the optimum combination of properties required to build cost-effective structur...

Microstructure and Mechanical Properties of the Friction Welded Joint between X53CrMnNiN219 and X45CrSi93 Stainless Steel

Dissimilar metals friction welding of austenitic–martensitic stainless steels is commonly used in order to manufacture engine valves in the automobile industry. In this study, X53CrMnNiN219 (austenitic stainless steel) and X45CrSi93 (martensitic stainless steel) valve steel rods were welded by friction welding process. The welded joint was then heat treated at 760 0C for 60 min. Mechanical prop...

Yield & Tensile Strength of Steel & Aluminium Using Microindentation

The Influence of Ultrasonic Impact Treatment on Fatigue Behaviour of Welded Joints in High-strength Steel

The unabated growth of the steel industry and progressively increasing operating loads on metal structures generate a need for a search for optimum engineering solutions to improve the loadcarrying capacity and reduce metal consumption. One way of resolving this problem is to utilise high-strength steels. It is common knowledge however that the improvement of the steel strength is accompanied b...
