1. Development and Applications of Highly Functional Al-based Materials by Use of Metastable Phases
This paper reviews the features of alloy components, structure and mechanical properties, physical and chemical properties of metastable Al-based alloys developed by use of various liquid or vapor quenching-induced phases such as amorphous, quasicrystalline, nanocrystalline, nanocomposite, supersaturated solid solution and structure gradient phases. As advan

2. Numerical analysis of phase decomposition in A-B binary alloys using Cahn-Hilliard equations
The analysis of phase decomposition was carried out using the nonlinear and linear Cahn-Hilliard equations in a hypothetical A-B alloy system with a miscibility gap. These equations were solved by the explicit finite difference method assuming a regular solution model. The supersaturated solid solution and decomposed phases were considered to have an fcc str

3. A study of Al-Mo powder processing as a possible way to corrosion resistent aluminum-alloys
Elementary Al and Mo powder mixtures have been processed by high energy ball milling up to milling times of 100 hours. The shift of the pitting potential and the X ray analysis of green milled samples showed that part of the Mo has formed a supersaturated solid solution of Mo in Al. Elementary Mo powder, however, was still present after 100 hours of milling.

5. Decomposição spinodal de ligas do sistema Al-Si-Cu
A decomposição spinodal de ligas de alumínio do sistema Al-Si-Cu foi estudada a partir de diferentes condições termodinâmicas. Duas composições foram selecionadas: A1-1,5%Si- 1,0%Cu e A1-2,5%Si-1,0%Cu, com as composições em peso. Estas ligas foram elaboradas por fusão convecional num forno a gás (GLP) a partir de alumínio, cobre e silício, na c

6. Estudo espectroeletroquímico e eletroanalítico de banhos de eletrodeposição de ligas prata-cobre e pratazinco e caracterização morfológica, química e estrutural dos filmes / Electroanalytical and spectroelectrochemical study of electrodeposition baths of silver-copper and silver-zinc alloys and morphological, chemical, and structural characterization of the films
The purpose of this thesis was to establish the conditions for silver-copper and silver-zinc electrodeposition from ammonium hydroxide and thiourea solutions, respectively, and to investigate the effect of added EDTA and HEDTA on the electrodeposition process. In this way, the influence of solution composition and electrodeposition parameter (deposition pote

7. Efeito da substituição do molibdênio pelo nióbio e nióbio-boro em aços Hadfield no desempenho ao desgaste abrasivo
The aim of this research was to allow the development of these types of alloys for wear resistance, in order to promote the application of these alloys in economic terms and mechanical properties. Nowadays, with the high prices of some materials, mainly those with molybdenum, both ferro-alloy as oxide, there is a bigger and bigger necessity in to develop new

8. The effects of mechanical alloying on the extrusion process of AA 6061 alloy reinforced with Si3N4
The synthesis of materials by high energy ball milling of powders was first developed for the production of complex oxide dispersion-strengthened nickel alloys for structural, high temperature applications but has been attracting attention in the field of fabrication processes like the production of intermetallic compounds, supersaturated solid solutions, am
