Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

The closed-loop kinematics modeling and numerical calculation of the parallel hexapod robot in space
Advances in Mechanical Engineering, 2017 The Lie group Denavit–Hartenberg method and application in the parallel hexapod robot are researched. The hexapod robot and the ground form opened and closed loop alternately; the complete kinematics equation cannot be derived by Denavit–Hartenberg ...

Disconnected groups of Lie type as Galois groups.
Journal für die reine und angewandte Mathematik (Crelles Journal), 1992 A large part of the finite simple groups have been shown to occur as regular Galois groups over the field \(\mathbb{Q}^{ab}(t)\). For the groups of Lie type, these are results of Belyj and of the author. The only missing cases are among the exceptional groups of Lie type, and there only some cases in bad characteristic and one congruence class \(\hbox ...

Character value estimates for groups of Lie type [PDF]
Pacific Journal of Mathematics, 1991 Let \(G\) be a finite group of Lie-type defined over a field with \(q\) elements, let \(\chi\) be a non-linear irreducible character over the complex numbers and let \(x\in G\) be semisimple of prime order modulo \(Z(G)\). Apart from some exceptions in characteristic 2 and 3 the author establishes a universal bound \(C\) independent of \(G\), \(\chi ...

Advanced Engineering Materials, EarlyView.Phase diagrams of transition‐metal di‐pnictides have been efficiently and quickly explored by combinatorial deposition of transition‐metal films and subsequent antimonization enabling the study of compounds with volatile elements. In (Fe,Ni)Sb2 and the (Fe,Cr)Sb2 substitution series, phase separation has been evidenced between class‐A and B marcasites ...

Advanced Engineering Materials, EarlyView.The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...
