A Phosphonic Functionalized Biopolymer for the Sorption of Lanthanum (III) and Application in the Recovery of Rare Earth Elements (open access)

A Phosphonic Functionalized Biopolymer for the Sorption of Lanthanum (III) and Application in the Recovery of Rare Earth Elements

Authors of the article state that in the first step of their experiment, the sorption was investigated using La(III) ions before testing for the recovery of rare earth elements (REEs) from pretreated industrial acidic leachate. They infer that phosphonate groups participate in the sorption, and that the most effective sorption is at pH = 4.

Microstructure evolution and mechanical properties in a gas tungsten arc welded Fe42Mn28Co10Cr15Si5 metastable high entropy alloy (open access)

Microstructure evolution and mechanical properties in a gas tungsten arc welded Fe42Mn28Co10Cr15Si5 metastable high entropy alloy

Article asserts that weldability studies on high entropy alloys are still relatively scarce, delaying the deployment of these materials into real-life applications, thus, there is an urgent need for in-depth studies of the weldability of these novel advanced engineering alloys. In the current work, an as-cast Fe42Mn28Co10Cr15Si5 metastable high entropy alloy was welded for the first time using gas tungsten arc welding.

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.

Room and Elevated Temperature Sliding Friction and Wear Behavior of Al0.3CoFeCrNi and Al0.3CuFeCrNi2 High Entropy Alloys

Article discusses how, in this study, processing–structure–property relations were systematically investigated at room and elevated temperatures for two FCC Al0.3CoFeCrNi and Al0.3CuFeCrNi2 high-entropy alloys (HEAs), also known as complex concentrated alloys (CCAs), prepared by conventional arc-melting. It was determined that both alloys exhibit FCC single-phase solid solution structure. Micro-indentation and sliding wear tests were performed to study the hardness and tribological behavior and mechanisms at room and elevated temperatures.
