The unique structure and formation mechanism of medium-entropy alloys (MEAs) generally result in better comprehensive properties than traditional alloys. However, the strength-ductility trade-off remains a bottleneck, which limits their applications. In this study, we designed novel high-performance CrNiCux MEAs with heterophase composition by incorporating Cu-rich phase, they were fabricated using laser-directed energy deposition (LDED). results show that synergistic strengthening from...
Abstract Dissimilar metals have exceptional development prospects in many fields due to their unique properties. However, the formation of brittle intermetallic compounds (IMCs) dissimilar significantly reduces bonding strength and causes interface cracking. In this study, a novel solid solution design concept is proposed solve problem. And ultrahigh TC4 titanium alloy/316L stainless steel metal achieved through additive manufacturing, with CrCuV alloy interlayer. By utilizing high‐entropy...
The Cu alloying strategy can substantially enhance the creep rupture strength of martensite ferritic steel (MFS), yet precipitation tailoring and hardening mechanisms remain not fully understood. This study examines ε‐Cu mechanism phase modulation in 9Cr MFS with varying concentrations 0.5, 1.0, 1.5 wt% during aging at 650 °C. results indicate that solute atoms hardly contribute to solid solution hardening, whereas nano scale particles could hardness. As content increases, austenite...
Femtosecond laser drilling is extensively used to create film-cooling holes in aero-engine turbine blade processing. Investigating and exploring the impact of processing parameters on achieving high-quality crucial. The traditional trial-and-error approach, which relies experiments, time-consuming has limited optimization capabilities for holes. To address this issue, paper proposes a process design method using machine learning genetic algorithm. A dataset percussion femtosecond was...
To avoid brittle intermetallic compounds during direct connection of the Ti-6Al-4V alloy and 316L stainless steel, FeCrCuV medium entropy (MEA) is designed as transition layer, 316L/FeCrCuV/Ti-6Al-4V dissimilar materials are fabricated by laser metal deposition (LMD). The heterogeneous interfaces 316L/FeCrCuV FeCrCuV/Ti-6Al-4V investigated a scanning electron microscope (SEM), an energy dispersive spectroscope, backscatter diffraction. results indicate that common TiFe TiFe2 at...
The material performance simulation software JMatPro was used to simulate and calculate equilibrium phase structure properties of a mixture formed by mixing different proportions Norem02 alloy F304 stainless steel. results show that in the range 500-1300 °C, phases include Austenite Ferrite, carbides M 2 (C,N), 6 C, 7 C 3 23 . As content increases, transition temperature A 1 decreases, <mml:math...
High-density MX precipitates block the movement of dislocations during creep at high temperature and increase sink strength to point defects under irradiation. Therefore, precipitation control phase is crucial for advancement reduced activation ferritic/martensitic (RAFM) steels. In this paper, an optimized two-step austenitizing strategy was proposed enhance Ta(C, N) in RAFM steels, effects first second on enhancement were studied. During austenitizing, particles with a small radius (∼12...
Laser direct energy deposition (LDED) exhibits great potential for application in rail repairing due to its low cost and high process automation. However, the martensite transformation accompanied by rapid solidification leads decrease mechanical properties threatens service safety. In this study, reinforcement strategy of combining cobalt (Co) addition with preheating treatment was investigated systematically thermodynamic calculations experimental characterization optimize microstructure...
Data augmentation and other training techniques have improved the performance of deep learning segmentation methods for steel materials. However, these often depend on dataset do not provide general principles segmenting different microstructural morphologies. In this work, we collected 64 granular carbide images (2048 × 1536 pixels) 26 blocky ferrite (2560 1756 pixels). We used five two derived from them test set to investigate influence frequently model accuracy. propose a novel method...
