HIGH TEMPERATURE CREEP OF SILVER,

Abstract

Experimental results indicate that the apparent activation energy for the steady state or minimum rate creep of silver is not independent of stress and temperature at temperatures well in excess of half the melting point. At sufficiently high temperatures there is a transition from a region in which the apparent activation energy is about 43.8 Kcal/mole, roughly equivalent to that for self diffusion (45 to 46 Kcal/mole), to one in which it is 65 or more Kcal/mole. The higher value of apparent activation energy is extended to lower temperatures at greater values of stress. (Author)
