Journal ArticleDOI
Effect of weld metal chemistry and heat input on the structure and properties of duplex stainless steel welds
TL;DR: In this article, a low heat input process viz., EBW and another commonly employed process, gas tungsten-arc welding have been employed for welding of duplex stainless steels with and without nickel enhancement.
Journal ArticleDOI
Effect of nickel and nitrogen addition on the microstructure and mechanical properties of power beam processed duplex stainless steel (UNS 31803) weld metals
TL;DR: In this paper, the joining of duplex stainless steel was attempted by electron beam and laser beam welding, introducing nickel and nitrogen into the weld metals by different means, but it seems to have no appreciable influence on hardness.
Journal ArticleDOI
Microstructure and Mechanical Properties of Weld Fusion Zones in Modified 9Cr-1Mo Steel
TL;DR: In this article, a plate of modified 9Cr-1Mo steel was welded with three different filler materials: standard 9Cr 1Mo, modified 9 Cr 1Mo and nickel-base alloy Inconel 182 post-weld heat treatment (PWHT) for periods of 2 and 6 hours.
Journal ArticleDOI
Microstructure and Mechanical Properties of 9Cr-1Mo Steel Weld Fusion Zones as a Function of Weld Metal Composition
TL;DR: In this article, microstructural studies and Charpy V-notch impact testing were carried out on welds to understand the factors influencing toughness, and it can be concluded that reducing vanadium and niobium weld metal toughness can be improved.
Journal ArticleDOI
Optimization of compound layer thickness for wear resistance of nitrocarburized H11 steels
TL;DR: In this paper, higher treatment temperatures were employed in a Sursulf salt bath to increase the layer thickness and the wear resistance of treated specimens assessed using pin-on-disc test geometry.
