Hastelloy C276 alloy, a typical Ni-based solid solution strengthened trademark superalloy, possesses excellent practical performance under severe environmental conditions and elevated temperatures. Hence, Hastelloy C276 has been investigated as a candidate for structural material for nuclear reactors, chemical processing and aerospace, particularly as aero-engine components. Wire arc additive manufacturing (WAAM), with its relatively high deposition efficiencies and cost-effectiveness, is revolu...

Transition-metal alloys are currently drawing increasing attention as promising electrocatalysts for the alkaline hydrogen evolution reaction (HER). However, traditional density-functional-theory-derived d-band theory fails to describe the hydrogen adsorption energy (ΔGH) on hollow sites. Herein, by studying the ΔGH for a series of Ni−M (M=Ti, V, Cr, Mn, Fe, Co, Cu, Zn, Mo, W) bimetallic alloys, an improved d-band center was provided and a potential NiCu electrocatalyst with a near-optimal �...
