In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Why are all dualities conformal? Theory and practical consequences
Nuclear Physics B, 2015 We relate duality mappings to the “Babbage equation” F(F(z))=z, with F a map linking weak- to strong-coupling theories and demonstrate that, under fairly general conditions, F may only be a specific conformal transformation of the fractional linear type.

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion
Advanced Engineering Materials, EarlyView.Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

On the continuity of the commutative limit of the 4d N=4 non-commutative super Yang–Mills theory
Nuclear Physics B, 2015 We study the commutative limit of the non-commutative maximally supersymmetric Yang–Mills theory in four dimensions (N=4 SYM), where non-commutativity is introduced in the two spacelike directions.

Advanced Engineering Materials, EarlyView.Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

Advanced Engineering Materials, EarlyView.Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Morphisms and Duality for Polarities and Lattices with Operators
FLAP, 2019 Structures based on polarities have been used to provide relational semantics for propositional logics that are modelled algebraically by non-distributive lattices with additional operators. This article develops a first order notion of morphism between polarity-based structures that generalises the theory of bounded morphisms for Boolean modal logics.

Advanced Engineering Materials, EarlyView.This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Distributive Lattices, Bipartite Graphs and Alexander Duality [PDF]
Journal of Algebraic Combinatorics, 2005 In the paper under review, a certain squarefree monomial ideal \(H_{P}\) arising from a finite partially ordered set \(P\) is studied from the viewpoints of both commutative algebra and combinatorics. It is shown that the defining ideal of the Rees algebra \(R(H_{P})\) of \(H_{P}\) possesses a reduced Gröbner basis consisting of quadratic binomials ...
