1. Length Scale of the Dendritic Array Tailoring Strength of a 5052 Aluminum Alloy
The present research aims to characterize 5xxx alloy series, considering chemistries based on the commercial 5052 alloy with three Mg contents (2.4wt.%, 2.6wt.% and 3.2wt.%) through transient directional solidification experiments. Very representative incoming impurities to a given twin-roll casting procedure were reached. As such, the Si, Fe, Cu, Mn and Cr-

2. Numerical Analysis of Twin-Roll Casting of Strips With Profiled Cross-Section
The relatively high production costs of innovative materials with tailored properties such as Tailor Welded Blanks, Patchwork Blanks, Tailor Heat Treated Blanks and Tailor Rolled Blanks are responsible for a growing interest in new cost-effective production methods. One of the promising energy-saving and environmental friendly technologies for the production

3. Effect of casting mode and thermal treatments on the electrical conductivity of the AA4006 aluminum alloy
Abstract Initially studied was the effect of the casting mode on the electrical conductivity of AA4006 aluminum alloy sheets produced by both Twin Roll Casting (TRC) and by the semi-continuous Direct Chill (DC) industrial processes, when compared to sheets with commercial purity (AA1050) and high purity aluminum (AA1199). Then, the effects of heat treatments

4. Effect of Warm Rolling on Microstructure and Mechanical Properties of Twin-roll Casted ZK60 Alloy Sheets
In this study, ZK60 magnesium alloy strips were produced by twin roll casting (TRC) and then subjected to warm rolling at the temperature of 300 °C and 350 °C. Rolled sheets related to different rolling reductions were prepared after sequential warm rolling with the rolling speed of 5 m/min. Microstructures, texture, hardness, tensile properties of the rol

5. Texture analysis of cold rolled and annealed aluminum alloy produced by twin-roll casting
A 7.4 mm thick strip of 3003 aluminum alloy produced by the industrial twin-roll casting (TRC) process was homogenized at 500 °C for 12 hours, after which it was cold rolled in two conditions: 1) to reduce the strip's thickness by 67%, and 2) to reduce it by 91%. The alloy was annealed at 400 °C for 1 hour in both conditions. The results revealed that a ro

6. Um estudo comparativo sobre a recristalização de chapas de alumínio AA1200 e AA3003 obtidas por lingotamento contínuo (twin roll caster) e por fundição de placas (direct chill). / A comparative recrystallization study of aluminium sheet AA1200 and AA3003 obtained by continuous casting (twin roll caster) and by casting of plates (direct chill).
A necessidade de redução de custos de produção torna o caster mais vantajoso que o processo de placas, porém a aplicação dos produtos obtidos via vazamento contínuo é limitada pelas condições microestruturais. A alta taxa de resfriamento no processo de vazamento, que pode ultrapassar 300 °C/s, resulta em uma condição de supersaturação dos ele

7. 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

8. Estudo do comportamento mecÃnico da liga de alumÃnio AA 8011 em diferentes seqÃÃncias termomecÃnicas
Sheets and foils of AA 8011 aluminum alloy, among other properties, exhibit a typical mechanical behavior in which formability and mechanical strength establish a good compromise, which is normally not encountered in other commercial aluminium alloys. These characteristics make possible use of this aluminum alloy in different products as alimentary packaging

9. A inserção de tecnicas de inteligencia artificial na modelagem matematica do lingotamento continuo de aços
The control of quality of products produced by continuous casting can not be achieved without a knowledge base of the process, which incorporates parameters and variables influence such as: equipment, cast metal, behavior of each component of the cooling system and operational conditions. This work presents the development of a computational algorithm (softw

11. Simulation of thin strip continuous casting of steels / Simulação do lingotamento continuo de tiras finas de aços
It can be understood by process modeling the development of a quantitative or qualitative representation of the physical phenomena associated to the process. In this work, simulations concerning the twin roll continuous caster of steels process at IPT (Instituto de Pesquisas Tecnológicas do Estado de São Paulo) are performed. Two simulators were developed:
