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.

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Thermodynamic model for lattice point defect-mediated semi-coherent precipitation in alloys
Communications Materials, 2021 Precipitation of secondary phases in a crystalline matrix often leads to the loss of coherency at the phase boundary. Here, a thermodynamic model for precipitation is presented that takes into account the role of lattice point defects on the ...

Coherent-to-semi-coherent transition of precipitates in niobium-hydrogen thin films
Physical Review B, 2008 Nucleation and growth in thin films are studied by using niobium-hydrogen (Nb-H) as model system. Hydride precipitation in thin films results in local surface topography changes that can be monitored by scanning tunneling microscopy. The local film expansion can be used to detect hydride precipitates, to study their growth, to gain information about ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Strain localisation and failure at twin-boundary complexions in nickel-based superalloys
Nature Communications, 2020 Coherent twin boundaries in nickel-based superalloys are vulnerable sites for alloy failure in demanding environments. Here, the authors show that the abnormal γ″ precipitation mechanism at twin boundaries is responsible for pronounced strain ...

Coherent precipitation strengthening by/in LI2-ordered phases
Journal de Physique III, 1991 Microstructural characteristics of (i) the alloys strengthened by precipitation of a coherent LI2-ordered phase and (ii) the LI2-ordered alloys strengthened by the precipitation of coherent disordered phase are reviewed with particular emphasis on the effects of volume fraction and morphology of second phase.
