High entropy alloys (HEAs), consisting of five or more elements with nearly equal atomic composition one another (5–35%), are new-generation that have attracted significant interest since their advent in 2004 because unique structural and mechanical properties thermodynamic chemical stability. Some characteristics, including high strength at elevated temperatures, ductility fracture toughness cryogenic temperatures corrosion, erosion wear resistance, been demonstrated for HEAs outperform...
Material degradation of metal alloys usually starts from the surface induced by tribological systems along with extremities including elevated temperatures, irradiations, erosion, corrosion, etc. Surface engineering, e.g. cold-working, carbonization, nitridation, etc., and coating are distinct routes that have been developed to protect metallic components. Laser cladding is an advanced method produce build them up layer-by-layer, which has advantage being feasible in digitalizing materials...
The ability of additive manufacturing processes to control solidification at a microscopic scale is particular interest in the development components with topology-optimised microstructures. Leveraging laser powder bed fusion (L-PBF), we present new methodology develop site-specific "microstructure architectures" consisting dissimilar phases. By controlling focal offset bespoke L-PBF machine, tailor melt pool shape and volume material that undergoes re-heating during each melting event....
The past two decades have witnessed extensive explorations of boron nitride (BN) largely due to its unique optoelectronic properties, mechanical robustness, high thermal conductivity, and chemical stability. Crystal growth functional engineering BN thin film structures as well their integrations with two-dimensional materials for advanced applications been attracting increasing interest in recent years. Here, we reviewed the basic structural, electronic, transport properties BN, especially...
Abstract Scanning of a high-power laser beam on the surface martensitic stainless steel (SS420) has been studied, addressing effect scanning rate V integrity modifications in near-surface regions. Structural, compositional, and crystallographic characterizations revealed presence ablations, melting/resolidification, oxidations, austenite ( γ -phase) precipitations when ≤ 20 mm s −1 . Melt pool (MP), heat affected zone (HAZ), base material have clearly distinguished at cross-section...
Surface enhancement and coating are distinct methods that have long been developed for protecting metallic components from corrosion, erosion, wear in aggressive working environments. The former is to engineer the surface near-surface of base material towards desired performance improvements. In comparison, a deposit extrinsic materials with better-desired direct on material. Recent developments additive manufacturing rendered increased interest hybrid process coating. Here, we report...
