摘要：

In this study, we present a systematic investigation into the influence of solidification direction on the thermodynamic parameters and mechanical damping capacity of a CuAlBeNbNi alloy solidified in a unidirectional manner. Additionally, we assess the effects of loading rate and the number of loading-unloading cycles during ultramicrohardness tests on the damping capacity in mechanical assessments. The results demonstrate an anisotropic behavior both in the thermodynamic parameters of the martensitic transformation and in the mechanical damping capacity of the CuAlBeNbNi alloy (produced through directional solidification), highlighting the necessity to consider the solidification direction's influence in the design of technological devices.
