In previous investigations, it was reported that transition metal-rich amorphous alloys consist of distorted bcc nano-clusters. Two types of amorphous metals are of interest due to their physical properties: (1) metallic glasses and (2) nanoglasses.

Strengthening of metals by grain refinement is limited by the inverse Hall-Petch effect. Here, the authors show nanograined metals can be strengthened by exhausting lattice dislocations via triggering of phase transformation at grain boundaries, inst

Nanostructured materials are being actively developed, while it remains an open question how to rapidly scale them up to bulk engineering materials for broad industrial applications. This study propose an industrial approach to rapidly fabricate high

The structural stability of Fe90Sc10 nanoglasses has been studied by means of low temperature crystallization. Specimens were annealed in situ in a transmission electron microscope, and ex situ in an ultra-high vacuum tube-furnace. Both studies led t

Fe75Zr25/Cu64Zr36 amorphous multilayers were prepared by magnetron sputtering. Atom probe tomography was employed to analyze the atomic inter-diffusion at the interface of the multilayers before and after annealing (573 K, 60 min). An unexpected enha

Ni-P nanoglass consisting of nanometer-sized amorphous grains separated by amorphous interfaces was prepared by a specially designed multi-phase pulsed electrodeposition technique. The microstructure of the deposited Ni-P nanoglass was confirmed by X

Grain/interphase boundaries/interfaces of varying misorientations, free volume fractions, curvatures and irregularities are present in materials, both 3D and 2D, regardless of whether these materials are crystalline or amorphous/glassy. Therefore, a

Nanoglasses are a new class of noncrystalline solids. They differ from today’s glasses due to their microstructure that resembles the microstructure of polycrystals. They consist of regions with a melt-quenched glassy structure connected by interfa
