This study systematically investigates the effects of carburizing and carbonitriding temperatures on microstructural evolution wear resistance 18Cr2Ni4WA steel. The surface layer after carburizing–carbonitriding treatment comprises acicular/lath martensite, residual austenite, dispersed carbides, with gradients dependent processing parameters. Elevated (930–970 °C 850 carbonitriding) marginally reduce microhardness harden depth, while increasing temperature to 880 (930 carburizing)...
This study introduces a novel approach to optimize the weldability of AlSi‐coated press‐hardened 22MnB5 steel, focusing on effects preheating treatment coating microstructure. Despite extensive research heat during hot stamping, impact prior resistance spot welding structure and quality remains unexplored. By analyzing evolution microstructure at various temperatures durations, unique phase transformations within AlSi are revealed, with altering composition sheet resistance. Below 750 °C,...
Purpose Laser additive manufacturing (LAM) technology based on powder bed has been used to manufacture complex geometrical components. In this study, IN625 superalloys were fabricated by high-power fiber laser without cracks, bounding errors or porosity. Meanwhile, the objectives of paper are systemically investigate microstructures, micro-hardness and precipitated Laves phase deposited-IN625 under different annealing temperatures. Design/methodology/approach The effects temperatures...
Through the idea of replacing Ni with Mn, a shortened process ultra-fast cooling and two-step intercritical annealing for medium-Mn low-Ni steel after rolling was designed. Microstructures were characterized through optical microscopy, electron probe micro analyzer, scanning backscattered diffraction, X-ray diffractometer. Furthermore, effects different temperatures on austenite including content, stability, impact toughness experimental investigated. The microstructures comprised retained...
Graphene has recently garnered significant attention as an exceptional nanofiller for aluminum (Al) matrix composites due to its remarkable mechanical strength, elevated thermal and electrical conductivities. For practical industrial applications, it is necessary develop large-scale production technology. To this end, we have utilized a scalable stir-casting process fabricate graphene-reinforced composites. The microstructure, properties, conductivities of the with varying graphene contents...
Ni foils with various thickness were used as interlayer to achieve the laser tailored welding of 22MnB5 press-hardened steel (PHS) Al-Si coating. The effect content on microstructure, hardness and strength studied. results showed that reduced solidified primary δ phase in fusion zone, promoted transformation from into γ phase. ferrite was absent 4.7–19.5 wt.%. In addition, zone region during post-weld heat treatment at 950℃ because can reduce Ac3 temperature (the all transformed austenite)....
This present work is the first investigation on laser welding of novel hot-stamped steel with 2000MPa (HSS2000). Softening was in mixed-grain HAZ and tempered zone, due to martensite transformation, precipitated carbons partial recovery lath. Tensile strength welded joint ∼1500 MPa, 80% base metal, presence soften zone. However, softening cannot be eliminated decreasing heat input but it did not influence tensile joints. Thus, HSS2000 acceptable range 67∼86 J/mm because can reach 1500 which...
