Design and Production of a New FeCoNiCrAlCu High-Entropy Alloy: Influence of Powder Production Method on Sintering.

The structure of FeCoNiCrAl1.8Cu0.5 high-entropy alloys (HEA) obtained by two different routes has been studied.

Evidence of disruption of Si-rich microstructure in engineering-lightweight Al-12.2at.%Si alloy melt above liquidus temperature.

The exploration of microstructures in high temperature alloy melts is important for manufacturing of metallic components but extremely challenging. Here, we report experimental evidence of the disruption of Si-rich microstructure in engineering-lightweight Al-12.2at.

Solid-state amorphization of a quenched high-pressure GaSb phase studied by real-time neutron diffraction: evolution of the crystalline phase.

The amorphization of a quenched sample of the GaSb-II high-pressure phase was studied at ambient pressure by real-time neutron diffraction in the course of the sample heating from 100 K to room temperature at a rate of 0.4 K min(-1). The transformation to the amorphous state begins at 140 K and is completed near room temperature.

Identification of phases in gas-atomised droplets by combination of neutron and X-ray diffraction techniques with atom probe tomography.

Powders of Al(68.5)Ni(31.5) alloy have been produced by gas atomisation and sieved in different grain size families.
