Crystallographic Texture of Induction-welded and Heat-treated Pipeline Steel
نویسنده
چکیده
The Charpy energy of the sample after heat–treatment was significantly higher than the as–welded sample when the V–notches were located 1 or 3 mm away from FL. However, when the V–notch was located on FL, the improvement in toughness from the heat treatment was not so obvious with no enhancement noted for the test temperature of −40 ◦C. Under this condition, the facets of the fracture surface are in the size of 0.2 μm.

Effect of Heat Input of Submerged Arc Welding Process on the Corrosion Behavior of API X42 Gas Pipeline Steel Weld Joint
The effect of heat input of submerged arc welding process on the corrosion bahavior of weld metal of API X42 gas pipeline steel weld joint was investigated. For this purpose, 6 annealed sheets of 15mm thickness were prepared from the X42 microalloyed steel. Submerged arc welding process with varying heat input of 37.8, 18.9 and 12.6 kJ/mm was used for joint welding. Then potentiodynamic polariz...

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...
متن کاملMicrostructure and Crystallographic Texture Characterization of Friction Stir Welded Thin AA2024 Aluminum Alloy
Friction stir welding (FSW) is a promising technique to join aluminum alloys without having problems encountered during fusion welding processes. In the present work, the evolution of microstructure and texture in friction stir welded thin AA2024 aluminum alloy are examined by electron backscattered diffraction (EBSD) technique. The sheets with 0.8 mm thickness were successfully welded by frict...
متن کاملInfluence of rotational speed on the development of microstructure in a friction stir welded 304 austenitic stainless steel
Friction stir welding was conducted on AISI 304 austenitic stainless steel sheet with dimensions of 100 mm × 100 mm × 2 mm. The FSW was performed at a welding speed of 150 mm/min and rotational speeds of 400 and 800 rpm. The results showed that high frequency of low angle grain boundaries (LAGBs) were formed through dynamic recovery in the thermo-mechanically affected zone (TMAZ). Higher amoun...
