Interfacial conditions for thermomechanical equilibrium in two‐phase crystals
TL;DR: In this article, a virtual variational approach is used to deduce the interfacial conditions for thermomechanical equilibrium in two-phase crystals separated by a curved interface, and conditions necessary for equilibrium are obtained for both a coherent and incoherent interface that incorporate the effects of surface stress.

High-strength Zr-based bulk amorphous alloys containing nanocrystalline and nanoquasicrystalline particles
TL;DR: In this paper, the authors reviewed the properties of the nanocrystalline and nano-quasicrystalline Zr-based bulk alloys and found that the mechanical strength and ductility of the nonequilibrium phase bulk alloy are significantly improved by the formation of the nano-structures as compared with the corresponding amorphous single phase alloys.

Real-time observation of grain nucleation and growth during solidification of aluminium alloys
TL;DR: In this paper, the crystallisation kinetics of liquid aluminium-titanium alloys with microscopic TiB2 particles added to refine the grain size in the solidified material was studied by X-ray diffraction measurements at a synchrotron source.
