Due to the outstanding creep performance, nickel-based single crystal superalloys (Ni-SXs)
are extensively applied in modern aero-engine and industrial gas turbine. Apart from the …

The study of the mechanical properties of two-dimensional (2D) materials is one of the most
pursued areas of materials research. Nanoindentation, an experimental technique, is …

Sustainable and energy-efficient ammonia production requires facile nitrogen reduction for
hydrogen preservation and inorganic fertilizers. A nitrogen reduction apparatus with optimal …

Face-centered-cubic high-entropy alloys (HEAs) strengthened with coherent ordered
nanoprecipitates have demonstrated excellent strength-ductility synergy, even at elevated …

The present paper reports a new class of Co based superalloys that has γ–γ′
microstructure and exhibits much lower density compared to other commercially available …

Laser direct energy deposition (LDED) is a repair and remanufacturing technology that has
shown great potential, which is of significant importance for extending the lifespan of brake …

Electron beam powder bed fusion (E-PBF) can produce nickel-based superalloy
components with minimal cracking and post-processing. This is due to the reduced thermal …

The interdiffusivity of Al and the transition metal solutes Ti, V, Cr, Mn, Fe, Nb, Mo, Ru, Ta, W,
and Re in fcc Co is characterized at 1373 K, 1473 K and 1573 K by binary diffusion couples …

The paper presents the synthesis of a new class of γ–γ′ cobalt-based superalloy that is free
of tungsten as an alloying addition. It has much lower density and higher specific strength …

New polycrystalline Co-base superalloys with γ/γ′ microstructure have been developed,
which show excellent mechanical properties and enhanced oxidation behavior. The γ …
