Abstract
Accepted: 29.06.2016 It is known that copper has electrical and thermal conductivity. Therefore Cu-based alloys are used in technological and engineering applications. This paper is aimed at studying influence of various heat treatment on electrical resistivity properties of samples from binary Cu-Mn alloy. The chemical composition of the alloy was found to be Cu75.8-Mn24.2 (wt.%) by using energy dispersive x-ray analysis (EDAX) technique. Electrical resistivity is a fundamental property of many materials. Hence, it is a key physical property of all materials. The electrical properties of binary Cu-Mn system performed by using a standard four-point probe D.C. method A Keithley 2400 sourcemeter. The resistivity measurements are carried out in the temperature range from 50 to 300 °C during heating. In the measurements, important properties were observed. The values of electrical resistivity of alloy was determined as a function of temperature. The specific resistivity changed linearly with the temperature. The differents showed the resistivity as a function of quenching temperature. The relative values of electrical resistivity also increased with increasing rate of quenching.
