“…A similar experiment at lower stresses where Nichols has also suggested a loop-alignment model should be very informative, but would presumably require either better sensitivity than present in-pile creep machines supply or the significantly higher neutron fluxes available in other reactors, particularly fast reactors. Ion bombardment may be very useful in this regard also, for which creep machines are being designed at several laboratories [33].…”

Basic concepts felt to be important in diffusion-controlled creep of metals are reviewed and it is suggested that such creep is controlled by edgedislocation climb under a rather wide range of conditions. The effect of a damage-producing flux on such creep processes is explored. It is shown that processes such as Herring-Nabarro creep are unaffected by irradiation. Evidence is presented for a climb-plus-glide mechanism of radiation creep for stresses above unirradiated yield or flow stresses. At lower stresses a preferential dislocation loop nucleation model is suggested.
