STUDIES CONCERNING THERMAL CONDUCTIVITY FOR SOME COPPER BASE MEMORY SHAPE ALLOYS

The new applications of memory shape alloys impose a more precise characterization of the physical parameters. The paper presents the study of thermal conductivity on some memory shape alloys type CuZnAl and CuAlMnNi. The particular properties of memory shape alloys recommend their use for complex mechanical applications in domains as follows robotics, aeronautics, electric contacts. MATHIS TCi system allows direct determination of thermal conductivity and effusivity for different types of materials such as solids, liquids, powders, and pastes. Both types of copper-based alloys (CuZnAl is a brass and CuAlMnNi is aluminum bronze) with memory shape present good values for thermal conductivity, values specific to copper alloys.
