In this way, by quenching, the proportion of α and β' crystals changes compared to the initial microstructure obtained by casting, which directly affects the change in the properties of these alloys. The investigation in this paper was conducted to analyse the influence of quenching temperature on the thermal properties of CuZn40Pb2 alloy. After casting the alloy, it was heated at 500 °C, 600 °C, 700 °C, and 800 °C and cooled in ice water, to maintain the high-temperature structure. Microstructure was analysed using optical microscopy. The values of thermal diffusivity, specific heat, and thermal conductivity were determined for the alloy in the cast and quenched states. The sample that was quenched from 800 °C was subjected to continuous annealing during the DSC analysis showing two endothermic reactions characteristic for the melting of a lead phase and disordering of β' phase.enlead bronzethermal diffusivityspecific heatthermal conductivityconferenceObject
