The Origins of High-Entropy Alloy Contamination Induced by Mechanical Alloying and Sintering

Metals, 2020
One of the prevailing problems for materials produced by powder metallurgy is contamination from various sources. This work deals with the influence of process parameters and presence of process control agents (PCA) on the contamination level of ...

Formation of ethylene-vinyl acetate composites filled with Al–Cu–Fe and Al–Cu–Cr quasicrystallline particles

Journal of Materials Research and Technology, 2019
Icosahedral Al65Cu23Fe12 and decagonal Al73Cu11Cr16 quasicrystalline powders were synthesized by the mechanical alloying and subsequent annealing. Morphology evolution at mechanical alloying of Al-based powders was found to be determined by competition ...

Fabricating Homogeneous FeCoCrNi High-Entropy Alloys via SLM In Situ Alloying

Metals, 2021
Selective laser melting (SLM) in situ alloying is an effective way to design and fabricate novel materials in which the elemental powder is adopted as the raw material and micro-areas of elemental powder blend are alloyed synchronously in the forming ...

Alloying Mechanisms for Epitaxial Nanocrystals [PDF]

Physical Review Letters, 2007
The different mechanisms involved in the alloying of epitaxial nanocrystals are reported in this letter. Intermixing during growth, surface diffusion and intra-island diffusion were investigated by varying the growth conditions and annealing environments during chemical vapor deposition.

Cu-catalyzed Si-NWS grown on “carbon paper” as anodes for Li-ion cells [PDF]

, 2019
The very high theoretical capacity of the silicon (4200mAh/g more than 10 times larger than graphite), environmental-friendly, abundant and low-cost, makes it a potential candidate to replace graphite in high energy density Li-ion batteries.

Enhanced thermal stability and fracture toughness of TiAlN coatings by Cr, Nb and V-alloying [PDF]

, 2018
The effect of metal alloying on mechanical properties including hardness and fracture toughness were investigated in three alloys, Ti~0.33Al0.50(Me)~0.17N (Me¿=¿Cr, Nb and V), and compared to Ti0.50Al0.50N, in the as-deposited state and after annealing ...
