Effect of Temperature on the Tensile Strength and Thermoelectric e.m.f. Values of Aluminium Alloy

RN Egbu

Abstract


The tensile strength and thermoelectric e.m.f. values of 6063 aluminum alloy quenched at different temperatures from 2500C to 6000C were investigated. The result empirically confirmed that a perfect correlation exists between the tensile strength and thermoelectric e.m.f. values with concurrent minimum temperature values at about 4000C. Two distinct temperature range of heat treatments were identified; the low temperature heat treated materials (from 2500C to 4000C) yielded both higher tensile strength and thermoelectric e.m.f. values as against the high temperature (4500C to 600oC) heat treated materials. Significantly, these distinct temperature ranges of heat treated materials can be applied as transducer in electrically controlled heat processes
