We are grateful to Prof. C.P. Flynn for bringing to our attention the possible role of phonon-electron coupling in cascades. We also thank Prof. D.N. Seidman for numerous discussions. Our MD computer code was adapted from one developed by Prof. J.R. Beeler, Jr. The MD simulations were performed on the CRAY-2 at the MFE computer center under a grant from the US Department of Energy, Basic Energy Sciences. One of us (T.D.R.) is grateful to SUNY-Albany for a Presidential Graduate Fellowship. This work was supported by the US Department of Energy, Basic Energy Sciences under grants DE-AC02-76ER01198 and W-31-109-ENG-38, at the University of Illinois and Argonne National Laboratory, respectively.

N2 - This paper summarizes recent progress in the understanding of energetic displacement cascades and the primary state of damage in metals. On the theoretical side, the availability of supercomputers has greatly enhanced our ability to simulate cascades by molecular dynamics. Recent application of this simulation technique to Cu and Ni provides new insight into the dynamics of cascade processes. On the experimental side, new data on ion beam mixing and in situ electron microscopy studies of ion damage at low temperatures reveal the role of the thermodynamic properties of the material on cascade dynamics and structure.
