Internal frictions of several polycrystalline copper wires of various purities deformed at liquid nitrogen temperature and at room temperature were measured as a function of temperature between -190°C and + 20°C at about 1 c/s. There are three relaxation peaks in this temperature region and detailed
A study is made to determine the relationship between the KGster effect, i.e. the mod&s defect due to dislocations which is present in a freshly deformed sample and which subsequently anneals out, and the various low temperature relaxation peaks which have been observed. It is shown that the Koster
