摘要：

This paper deals with the influence of heat treatment (annealing, quenching, and aging) on the microstructure and mechanical properties of CuNi3Si alloy. CuNi3Si alloy is used in applications, where high electrical conductivity, thermal diffusivity and good mechanical properties are important. Heat treatment has profound impact on mechanical properties, as well as on electrical conductivity and thermal diffusivity. For this study, specimens were subjected to various heat treatment schedules and examined in light and scanning electron microscopes. Their mechanical properties were measured by hardness testing using Vickers scale. Thermal diffusivity was measured using laser flash method in LFA 1000 instrument made by LINSEIS GmbH. Hardness of the specimens ranged from 70 to 250 HV10. Their thermal conductivity was between 72 and 162 W/m.K. The lowest thermal conductivity was found in quenched specimens with the lowest hardness.
