Grain-boundary component in W-Ga composites: A way towards skeleton structures. Krauss, W. & Gleiter, H. Physical Review B, 58(17):11226--11231, November, 1998. WOS:000076716700037

Nanostructured materials consist of crystalline and grain-boundary components. In the simplest case, both components are chemically identical. Here, we present the results of a study of a system consisting of a crystalline component built by A atoms (tungsten) and a grain boundary component of B atoms (gallium). Within this system, component B is in a disordered state. Most likely, it exhibits an amorphouslike structure, and coats the tungsten crystals uniformly with a constant thickness, thus forming a Ga skeleton structure. The noncrystalline gallium seems to undergo no first-order structural phase transitions, e.g., no first-order melting transition was noted when the composite was below, at, or above the equilibrium melting point of Ga. The properties of gallium as a grain-boundary component differ significantly from those of crystalline and amorphous bulk gallium. [S0163-1829(98)03038-0].
