Estudo dos parâmetros termodinâmicos, microestrutura e microdureza de uma liga CuAlNi produzida com alumínio reciclado

Abstract

Currently, the use of materials with peculiar characteristics has been gaining its space in research and industry. Shape memory alloys are considered a smart material because of their ability to recover shape and superelasticity just by applying a predetermined force or thermal stress. In this work, two Cu-13Al-3Ni(%wt) alloys were produced: the first with pure aluminum and the second with recycled aluminum. Thermodynamic, microstructure and microhardness test studies were carried out in both samples in order to evaluate the influence, investigate the effect and evaluate the thermodynamic parameters of recycled Al in the Cu-13Al-3Ni alloy. Therefore, we can conclude that the results demonstrated in the study presented satisfactory and demonstrated the viability of the use of materials obtained through recycling, thus becoming an economical means of manufacturing.
