Polymorphic nature of {332} 〈 113 〉 twinning mode in BCC alloys (open access)

Polymorphic nature of {332} 〈 113 〉 twinning mode in BCC alloys

Article using ab initio calculations and experimental observations to show that {332}<113> twinning can be described as a polymorphic solid-state transformation able to produce either twinned or martensitic structures with a unified transformation path.

Lithium-CO2 batteries and beyond (open access)

Lithium-CO2 batteries and beyond

Article describes how Li-CO2 batteries with a theoretical energy density of 1,876 Wh kg−1 are attractive as a promising energy storage strategy and as an effective way to reduce greenhouse gas emissions by CO2 reduction and the formation of discharge product Li2CO3 and carbon. This article provides critical perspectives on the development of Li-CO2 batteries as well as a description of current issues and challenges associated with cathode catalysts, electrolyte, and anode for Li-CO2 batteries.

Laser powder bed fusion processing of a precipitation strengthenable FCC based high entropy alloy (open access)

Laser powder bed fusion processing of a precipitation strengthenable FCC based high entropy alloy

Article describes how, while additive manufacturing (AM) of single-phase solid solution based high entropy alloys (HEAs) has attracted a lot of recent attention, such processing of precipitation strengthenable multi-phase HEAs has not been actively investigated. This becomes important since AM processing results in each layer experiencing rapid solidification followed by multiple heating-cooling cycles, mimicking in situ heat treatments, potentially influencing the phase evolution.

Deformation behavior and strengthening effects of an eutectic AlCoCrFeNi2.1 high entropy alloy probed by in-situ synchrotron X-ray diffraction and post-mortem EBSD (open access)

Deformation behavior and strengthening effects of an eutectic AlCoCrFeNi2.1 high entropy alloy probed by in-situ synchrotron X-ray diffraction and post-mortem EBSD

Article describes how high energy synchrotron X-ray diffraction was used during tensile testing of an as-cast eutectic AlCoCrFeNi2.1 high entropy alloy. The authors determine for the first time the volume fractions of existing phases, and they further detail their role on the alloy deformation behavior.
