The Co-Cr-Fe-Ni high-entropy alloy (HEA) is particularly suitable for preparing coatings due to its excellent comprehensive properties. In this study, we use the laser cladding method prepare HEA with cable-type welding wire (CTWW) as filling material and investigated dilution rates of by experimental studies first-principles calculations. rate reduced about 50% changing feeding speed, a coating near nominal composition was prepared multi-layer cladding. successfully in fourth layer dense...
Hastelloy N alloy is an excellent oxidation and corrosion-resistant material, which selected as the shell material for main vessel of molten salt reactors (MSRs). In this work, we conducted double-sided gas tungsten arc welding (GTAW) on 4 mm thick plates to examine microstructure mechanical properties welded joints. The S-N curve was obtained by fatigue test. experimental results show that cracks initiate along weld toe propagate inward in a fan-shaped pattern. hardness highest...
A series of engineering application studies related to hydrogen damage has been carried out for the eutectic high-entropy alloy (HEA) AlCoCrFeNi2.1 with excellent comprehensive properties. This work mainly introduces element segregation and microstructure evolution phenomenon near surface phase boundary around precipitated found in experiment material. Studies have shown that near-surface HEAs caused by charging a great influence on trap density inside alloy. The "self-resistance effect" is...
