11.Dislocation creep generates strain rates which are easly observable in conventional creep tests only at temperatures higher than approximately 150 °C (see Ref. 9). The assumption made here thus extrapolates from data obtained at higher temperatures. The assumption is justified not only because it is consistent with the deformation maps developed by Ashby (Ref. 10) but also because dislocation creep is the only mechanism which allows a quantitative explanation of the contact growth rates observed in the present work. It is emphasized that the effects of dislocation creep are easily detectable in the present situation because they are highly localized.

13.This mode of contact growth could not be investigated in detail because it was observed only in 5 of over 200 experimental runs.
