摘要：
Ultra dispersed materials (UDM) such as thin films thin whiskers, fine powders, nanocrystals (NCs) have been designed. Calculated values of interatomic distances along various crystallographic directions are found to essentially decrease at the centre of the particle and much more reduced as the surface is approached. Similar changes of interplanar distances corresponding to an inhomogeneous distortion in UDM are confirmed experimentally, mainly by neutron diffraction. (C) 1999 Acta Metallurgica Inc.
