Review of the weldability window in explosive welding processes
Journal of Alloys and Metallurgical SystemsExplosive welding is a solid-state joining technique that employs explosive energy to propel the flyer plate into oblique collision with the base plate, forming a metallurgical bond at the interface. The process parameters, such as the loading ratio, the

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Effect of the Initial Grain Size on Laser Beam Weldability for High-Entropy Alloys
Crystals, 2022 This study investigated the effect of the initial grain size on the laser beam weldability of CoCrFeMnNi high-entropy alloys (HEAs). Cold-rolled, annealed, and cast HEAs with different initial grain sizes exhibited clear differences in weldability.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

The weldability of the steel with high manganese
Tehnicki vjesnik - Technical Gazette, 2016 Jedan od najvažnijih dijelova koji se danas koriste na željeznici su dijelovi na cestovnim prijelazima preko pruge i uglavnom dinamicka komponenta izložena djelovanju. Mangalloy, također poznat kao celik s manganom ili Hadfield celik, je celik s legurama koje u prosjeku sadrže 13 % mangana i jedinstven je po tome sto povezuje visoku žilavost i ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
