Various stability criteria developed for high-entropy alloys are applied to compositions produced by mechanical alloying. While they agree with the annealed samples, these fail describe as-milled metastable systems, highlighting ability of alloying overcome limitations imposed criteria. The based on atomic size (Ω ≥ 1.1 and δr ≤ 6.6%) and/or electronegativity misfit, as well mixing enthalpy (Λ>0.95 J mol−1K−1 −5 kJ mol−1<∆Hmix<0), or purely thermodynamic (ϕYe>20; ϕKing>1;...
Abstract Poly(vinylidene fluoride) (PVDF) is a piezoelectric and thermoplastic material with great potential for additive manufacturing (AM) applications. Using barium titanate (BaTiO 3 ) as filler, PVDF‐based composite materials were developed, characterized, processed by AM extrusion (MEX). The morphological features phase transformations occurring throughout the processing of BaTiO ‐filled PVDF, from compounding to printed part, analyzed. morphology powder feedstock after dispersion in...
