abstract = {In recent years, it has been shown that intra-cascade
clustering of vacancies and self-interstitial atoms (STAs),
differences in the thermal stability and mobility of the
resulting clusters and one-dimensional (1-D) diffusional
glide of SIA clusters play a key role in damage accumulation
in metals under cascade damage conditions. The model taking
these aspects into account (production bias model, PBM)
succeeded in rationalising striking features in the
microstructural evolution in pure metals, where the
conventional rate theory model failed: the high overall
swelling even at low dislocation densities, the enhanced
swelling near grain boundaries, the decoration of
dislocations with SIA loops, saturation of void growth and
Void lattice formation. In the present paper, the main ideas
and results of these considerations are reviewed. We discuss
recent work on possible effects of deviations of SIA cluster
diffusion from strictly 1-D by direction changes and/or
self-climb and formulate a general reaction kinetics
including 1-D and 3-D cluster diffusion. Such reaction
kinetics may be considered to form the basis for a general
description of cascade damage accumulation in metals and
complex technical alloys. (C) 2000 Elsevier Science B.V. All
