Abstract
The temperature transients arising from discontinuous slip in copper‐nickel alloys at helium temperature have been observed with thermometers of defined inertia properties. It is found that this type of slip can propagate through the specimen similar to a Luders band. In the discussed case, the temperature rises from approximately 5°K to approximately 35°K, and the mean value of the volume affected by each slip is 1.4×10−3 cm3. This volume corresponds very closely to the range of thermal diffusion during the time interval of slip. Thus, it is consistent with the assumption that discontinuous slip at low temperatures results from thermal feedback.This publication has 9 references indexed in Scilit:
