Thermoelectric Power and the Bauschinger Effect

Abstract

IT has been proposed^1,2 that the Bauschinger effect which occurs in face-centred cubic metals after a plastic strain exceeding 1 per cent might be attributed to the rearrangement of dislocations at the beginning of the reversal of strain. If we rather crudely reckon, that changes of thermoelectric power and electric resistance are measures of the total disorder in a lattice, then these should remain constant during the Bauschinger strain, though increasing during previous and subsequent plastic strain, because during the Bauschinger strain the total disorder in the lattice is not increasing, but merely being re-arranged.
