Abstract
This paper is aimed at studying influence of various heat treatments on transformation temperatures and electrical resistance properties of alloys from binary Cu–Mn system. It was noticed that with an increase in sample’s grain size, transformation temperatures also increased. The activation energies of samples were calculated according to Kissinger and Augis–Bennett. Thermogravimetric and differential thermal analysis measurements were used to investigate phase transformations and kinetic parameters. The electrical values of resistance of alloy were investigated at different temperatures. The resistance as a function of quenching temperature showed a decrease. Depending on quenching techniques, Cu–Mn alloy can display different product phases such as parent phase and precipitation.
