摘要：
Specimens of nearly stoichiometric CuAu and Cu3Au alloys were investigated by differential scanning calorimetry (DSC) and thermoresistometry during linear heating and cooling treatments between room temperature and 440-degrees-C (550-degrees-C). Several resistometric effects, unreported in previous works, were observed. The main aim of the study was to find the optimal way for the determination of the temperature T(C) for the order-disorder tranformation. We have found that its value determined by thermoresistometry is systematically lower than that found by DSC.
