Abstract: One of the major challenges of the automotive industry is the reduction of gas emissions combined with greater energy efficiency in vehicles, meaning the use of low-density materials is increasingly demanded. Among them, aluminum appears as an interesting alternative for use in vehicle components, as it combines mechanical properties Leia mais…

Abstract: This study aims to evaluate the influence of different annealing times on the microstructure and mechanical behaviour of C36000 brass. The specimens where heat-treated for 30 min to 480 min at 790 °C, followed by quenching in water. The microstructural and mechanical characterization was performed. The microstructural characterizations reveal Leia mais…

Resumo: O presente trabalho apresenta, de forma sintética, resultados selecionados de um extenso projeto no qual foram estudadas as principais propriedades de juntas para aplicação no setor automotivo e de transporte de carga. As juntas estudadas foram produzidas por quatro técnicas de união distintas: soldagem MIG, soldagem por FSW – Leia mais…

Abstract: This study aims to evaluate the influence of different annealing temperatures on the microstructure and mechanical behaviour of C36000 brass. The specimens were heat treated at temperatures ranging from 250°C to 850°C for 1 hour, followed by quenching in water. Afterward, the microstructural and mechanical characterization was performed.
