1. The Role of cobalt and nickel intermetallic phases on the mechanical properties and microstructure evolution of Al-Zn-Mg-Cu alloys
In this study, the effects of cobalt and nickel additions on microstructure evolution and mechanical properties of Al-Zn-Mg-Cu alloys produced by chill casting process were investigated. Al-Zn-Mg-Cu aluminum alloys containing Ni and Co additives were homogenized at different heat treatment conditions, aged at 120ºC for 24 h, and retrogressed at 180ºC for 3

2. Desenvolvimento de um sistema para detecção de dispersóides no ar
The amount of dust suspended in air can be harmful to human health if not complied with the limits previously established by the WHO (World Health Organisation). The air is polluted when it contains elements foreign to its natural composition: oxygen, nitrogen, noble gases and water vapor and even carbon dioxide. The most common forms of air pollution are ca

3. Evolução da microestrutura e da textura durante o processamento de chapas da liga Al-Mn-Fe-Si (3003) produzidas por lingotamento contínuo: um estudo comparativo com o processo semi-contínuo. / Microstructure and texture evolution of the Al-Mn-Fe-Si (3003) aluminum alloy produced from continuous casting process: comparative analysis with semi-continuous casting process.
The main reason for the development of this PhD Thesis was to compare the microstructures and textures of the 3003 aluminum alloy produced from continuous and semi-continuous casting processes. The roll caster process (continuous casting) has been increasingly used in the aluminum industry. Products usually obtained by means of heavy rolling operations in th
