• In situ design of advanced titanium alloy with concentration modulations by additive manufacturing

  Science · 2021-10-22 · 432 citations

  articleCorresponding

  Additive manufacturing is a revolutionary technology that offers a different pathway for material processing and design. However, innovations in either new materials or new processing technologies can seldom be successful without a synergistic combination. We demonstrate an in situ design approach to make alloys spatially modulated in concentration by using laser-powder bed fusion. We show that the partial homogenization of two dissimilar alloy melts—Ti-6Al-4V and a small amount of 316L stainles…

• Stress-dependent dislocation core structures leading to non-Schmid behavior

  Materials Research Letters · 2020 · 14 citations

  Senior authorCorresponding

  The stress-dependent core structures of dislocations for basal slip in magnesium are calculated using ab initio generalized stacking fault energy surface and microscopic phase-field method. The dissociation of dislocation cores exhibits the dependence on the non-shear component in the stress tensor; the Peierls stress is found to either become virtually zero or increase by an order of magnitude, depending on the applied shear stress magnitude and direction. The results, in contrast to the classi…

• Lattice distortion and atomic shuffle coupling of the R phase under grain size confinement in a Ni48Ti50Fe2 alloy

  Acta Materialia · 2025-04-15 · 10 citations

  articleOpen access

  The R phase in NiTi-based shape memory alloys is well known to exhibit a lattice distortion and an internal atomic shuffle relative to its parent B2 phase, yet over the past decades little is known of the correlation between these two structural changes. This study presents a first attempt to clarify their correlation in a nanocrystalline NiTiFe alloy. The lattice distortion produces a crystal shape change for the shape memory and pseudoelastic properties of these alloys and is subjected to the…
