Proposição de uma Nova Lei de Crescimento para Ligas do Sistema Monotético

Abstract

Monotectic alloys show promising applications in wear-resistant automotive components. This study proposes a new growth law for monotectic alloy systems, analyzing experimental results of unidirectional solidification under transient conditions. Growth laws as a function of position and velocity were established, allowing the evaluation of factors such as gravity and solute type on microstructure formation. The results indicate that monotectic growth does not follow the classical eutectic model, being significantly influenced by thermocapillary convection.
