Origin of the yield stress anomaly in L12 intermetallics unveiled with physically-informed machine-learning potentials [PDF]
arXivThe yield stress anomaly of L12 intermetallics such as Ni3Al or Ni3Ga is controlled by the so-called Kear-Wilsdorf lock (KWL), of which the formation and unlocking are governed by dislocation cross-slip. Despite the importance of L12 intermetallics for strengthening Ni-based superalloys, microscopic understanding of the KWL is limited.

Zeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 23, December 13, 2022., 2022 Abstract Ca14FeAs11 is the first iron‐containing representative of the Ca14AlSb11 structure type and the first compound with isolated FeAs4 tetrahedra. It can be regarded as a salt‐like compound containing isolated [FeAs4]9− tetrahedra, linear [As3]7− units, isolated As3− anions and Ca2+ cations and thus is a borderline compound between binary Fe−As ...

Determination of crystal structure and physical properties of Ru2Al5 intermetallic from first-principles calculations [PDF]
arXivNovel ordered intermetallic compounds have stimulated much interest. Ru-Al alloys are a prominent class of high-temperature structural materials, but the experimentally reported crystal structure of the intermetallic Ru2Al5 phase remains elusive and debatable.

Low‐Temperature Synthesis of NiSb2, Cu2Sb, InSb and Sb2Te3 Starting from the Elements
Zeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 23, December 13, 2022., 2022 Abstract Ionic liquids (ILs) are able to activate elements that are insoluble in common solvents. Here, the synthesis of binary antimony compounds directly from elements was explored. The 12 elements Ti−Cu, Al, Ga, In, and Te, known to form binary compounds with Sb, were reacted with Sb in [P66614]Cl under inert conditions in a closed glass flask with ...

Beyond Fundamental Building Blocks: Plasticity in Structurally Complex Crystals [PDF]
arXivIntermetallics, which encompass a wide range of compounds, often exhibit similar or closely related crystal structures, resulting in various intermetallic systems with structurally derivative phases. This study examines the hypothesis that deformation behavior can be transferred from fundamental building blocks to structurally related phases using the ...
