چکیده
A Gleeble thermo-mechanical simulator was used to simulate the welds of duplex stainless steel S32101. micro-precipitate chromium-nitride and its surroundings in simulated analyzed detail by SEM/AES EC-AFM. The AES analysis revealed that a chromium-depleted area is present γ phase near chromium-nitrides precipitated at α/γ grain boundary. EC-AFM observation preferentially dissolves from area.

Heat Affected Zone in Surfacing Chromium Ledeburitic Steel
Repair welding is not used enough in the industry 1 . One of the reasons for this lies in the insufficient and unrealiable knowledge in many segments of this area. A very important part is having appropriate knowledge of metallurgical processes in heating of the base material 2-4 . Unsuitable heating deteriorates the microstructure as it reduces toughness and fracture behaviour of the weld 5 . ...

The Influence of Heat-Input on Structural and Mechanical Properties of 2205 Duplex Stainless Steel
The influence of heat-input and pre-heat treatment on the structure, mechanical and corrosion behaviors of 2205 duplex stainless steel joint by means of GMAW process was the goal of this study. In this regards, the welding process was done using different heat input in the range of 0.6 to 1.4 kJ/mm and different pre-heating treatments in the range of 25 to 100 oC. The microstructural properties...
