Abstract: The effects of forced convection on the microstructure, macrostructure and macrosegregation of impurities in cylindrical ingots obtained by directional solidification of metallurgical grade silicon were examined. Two experiments were carried out, one without and another with the forced convection induced by a disk at the melt top rotating at Leia mais…
Resumo: A demanda da sociedade moderna por inovações tecnológicas, descarbonização e transição energética tem impulsionado o consumo de diversos metais como cobre, lítio, cobalto, níquel, elementos terras raras, além dos tradicionais ferro e alumínio. Estes metais são majoritariamente obtidos a partir de fontes primárias (jazidas minerais), no entanto, o desenvolvimento Leia mais…
Abstract: The pipe coating process follows a strict protocol in order to guarantee efficient mechanical and corrosive protection to pipes for onshore and offshore applications. However, its extremities must be exposed in order to enable its installation, making these regions sensitive to effects of the environment, mainly in tropical environments Leia mais…

Abstract: This study investigates the impact of the cooling rates, from 18 to 1.5 °C/s, on the as-cast microstructure of the CMSX-4 Ni-based superalloy, especially on morphological changes in primary γ′ precipitates in the dendrite core and border. Microstructural characterization along the height of directionally solidified samples included the measurement Leia mais…
