Estudio de la aleación inteligente con memoria de forma Cu-Zn para determinar su aplicación industrial

Abstract

In the present research work, the study of the intelligent alloy with Cu-Zn shape-memory was developed to determine its industrial application, five tests of casting with different quantities of alloying elements were conducted, mainly varying the quantities of Zn, until achieving a percentage of 59.32% Cu and 40.08% Zn, obtaining with this composition that the alloy behaves as an intelligent material with shape-memory, which returns to its predetermined form in the presence of an external stimulus, in this case the reaction to the presence of heat, it has characteristics such as superelasticity and thermal memory, the mechanical properties were determined based on ASTM standards, such as metallographic, traction, impact and hardness tests of the material obtained. In function of the properties achieved, an industrial application is given, proposing to use as a switch or actuator, which closes or opens a circuit when applying heat.
