The oxidation resistance of Mg-Zn-Zr (ZK60) alloys with the addition minor rare-earth element (RE) oxides (CeO2, La2O3) was investigated in 420ºC air and pure O2 environments. It revealed that behavior ZK60, ZK60-La2O3 ZK60-CeO2 is different. In comparison to typical intergranular ZK60 alloy, owing diverse phase transformations between La Mg, La-Mg continuously distributed grain boundaries, furthermore, a dense protective layer consisting intermetallic coated on surface, which can...
In this study, the processing parameters of a laser powder bed fusion (LPBF)-fabricated CoCrNi alloy were systematically investigated for their impact on mechanical properties, microstructure, and fracture characteristics when relative density exceeds 99%. The maximum 99.89% was attained at power 225 W, scan speed 1000 mm/s, accompanied by hardness value 276.83 HV. However, it is important to note that highest did not correspond σUTS. Tensile testing revealed increasing same speeds led...
The controlling strategies of grain morphology and mechanical properties Inconel 625 alloy by laser powder bed fusion are investigated, beyond that, the effects phase composition, morphology, crystallographic texture on also studied. evolution is insensitive to scanning strategies, all samples composed γ‐Ni phase. (001) orientation tends increase with rotation angle, sample IV fabricated 90° shows highest texture. Different morphologies can be tailored direction heat flow between continuous...
The bionic-inspired Ti–15Mo gradient porous structures were fabricated by selective laser melting (SLM) for the first time in this work. compression-compression fatigue behavior of functional is investigated, with emphasis on understanding relationship between performance and microstructure. microstructure samples was analyzed both before after fatigue, correlated performance. During cyclic deformation, pillars exhibited a non-uniform local stress distribution, primarily attributed to...
The microstructure evolution of near β-Ti alloys with initially lamellar and equiaxed microstructures subjected to dynamic loading was investigated. Results showed that during high strain rate compression, shear failure is more likely occur in microstructure. Owing temperature rise stress concentration, the α phase adiabatic band (ASB) zone recrystallized re-melted, while transformed strip-shaped following propagating direction band. During loading, twinning transfer observed between β...
Cobalt–manganese oxide is a promising electrode material for supercapacitors due to its high theoretical capacity. However, poor electrical conductivity and structural stability limit the energy storage capacity of Co–Mn material. Herein, an ultraviolet (UV) light radiation strategy proposed prepare nitrogen-doped mixed nanoarrays with enhanced electrochemical supercapacitors. were first prepared by hydrothermal method then irradiated UV lamp induce nitrogen doping. Because nanowire array...
