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 -190Β°C and + 20Β°C at about 1 c/s. There are three relaxation peaks in this temperature region and detailed
In this paper we report some observations on the grain boundary internal friction peak in polycrystalline aluminium after neutron irradiation at low doses. On neutron irradiation the grain boundary peak has been depressed and shifted to lower temperature side. This effect can be explained in terms o
