Abstract:
Formation of Cu-C composite
is a difficult technological problem: carbon is practically insoluble in
copper. We show that the heat treatment of the Cu-C composite leads to
the formation of a thin (approximately 50 nm) interface which provides
the bonding between fiber and matrix. The HR SEM study displays the formation
of small copper nano-crystals in the interaction zone. This structure of
the interface is predicted by molecular dynamic and Monte Carlo simulations
with semi-empirical repulsive Cu-C interatomic potentials. We show that
inclusion of a small amount of carbon in fee copper leads to strong deformation
of the copper host matrix in the vicinity of carbon. Decrease of stresses
in the lattice may be reached by the formation of the developed surface
in nano-crystalline structure. (C) 1999 Elsevier Science B.V. All rights
