TALAT Lecture 1101: Resources and Production of Aluminium
This lecture illustrates the natural abundance of the element and the history of its extraction from the ore; it shows the properties of pure aluminium, outlines the importance of alloys to commercial development and shows the range of alloys available and their classification; it describes the principal markets for aluminium; it illustrates the basic processes used in the production of primary aluminium and the main fabricating routes used to provide the products needed by manufacturing industr

ACADIA'99: media effect on architectural design
The idea of this conference arose from various discussions between us in various different places.?We decided to put a proposal together for both?positions?Technical Chairs and Site Organizers. This was unprecedented and we were anxious. We really wanted to run this conference and run it in Salt Lake City. Our theme AMedia and Design ProcessB was a timely topic and both of us were working on and around it. We thought it was interesting and challenging to define the terms and to establish the rel

Wrought-grade aluminium alloy
The micrograph shows Al-Mg-Fe-Si containing < 1wt.% of each solute; refined with TiB2 particles. Deformation of grain structure is due to cutting of sample with scissors. This micrograph illustrates the effect of deformation on a previously equiaxed structure. Strain causes the elongation of grains and the subsequent anodising produces 'mottled' grain colours; the oxide layer is not of constant orientation or thickness across a grain.The Barker's etch and applied electrical field produce a thick

Laboratorio proyectual (Design Laboratory)
The concern about public space, digital graphic and a non-habitual theoretical background are the elements of an on-process research this paper relates to. The premise of the research is the current uncertain experience of both socio-cultural and physical-spatial public space in an Argentinean intermediate city. The focus is a workshop carried out to explore how forms for the public space may be designed when urban conditions are unstable, such the case of vacant areas, lost places or terrain-va

Carbon-carbon composite
Carbon-carbon composites are manufactured from continuous carbon fibres which are woven in a two or three dimensional pattern. The fibres are then impregnated with a polymeric resin. After the component has been shaped and cured the matrix is pyrolysed by heating in an inert atmosphere. This converts the matrix to carbon chain molecules which are densified by further heat treatments. The resulting composite consists of the original carbon fibres in a carbon matrix. Carbon-carbon composites have

Dise?o Digital. Estudio Exploratorio de caso (Digital Design. Exploratory study of a case)
After the passage of the mechanical era to the digital era, the design must respond with increasing complexity of the technique, together with the plurality of expectations. Design education is sustained in conceptual instrumentation; it implies to recognize problematics that surpass the possibilities of an isolated or self-sufficient discipline; transdiscipline becomes essential for the understanding of the subjects.The porpuse is to generate new instruments for perception of space, combined wi

GESTI?N DIGITAL URBANA ROSARIO (Digital Management of Urban Rosario)
This project is aimed at developing an instrument to reach the city-net multidimensionality (flux /real-space) of Rosario city in Argentina. Both, an integral view and the view of the different information layers of the urban net are required. We decided the used of computers to determine a digital dynamic model. The tool proposed has to be useful not only in search and urban survey but also as a design instrument, to pre-view the urban interventions. Simultaneously this tool is needed to evalua

Cross-section of an aluminium foam slab produced by gas injection
This is a continuous casting process which obviates foaming agents and the restrictions that they impose on temperature and processing time. However, molten metal drains through the structure due to gravitational forces and the resulting foam has a pronounced density gradient.

Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE)
FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor. In this case, grains of 1-4mm diameter have been sintered at 600 degrees C for just 10 minutes, giving rise to lightly

FORMGRIP closed cell aluminium foam
Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% of pre-oxidised titanium hydride is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a relatively fine and uniform cell structure.

Space-filling fire-resistant composite Barrikade (R)
The concertina-like structure of the exfoliated vermiculite particles is clear. This configuration is set by the binder during the initial cure. This is then followed by a moulding operation and secondary, inter-particulate binding.

Deeply etched dendrites (cobalt samarium copper)
Using this alloy composition, a relatively low volume fraction of pro-eutectic dendrites are formed. The eutectic material between these dendrites can be etched away to reveal the three-dimensional structure of dendrites. The dendrite tips are a volume of revolution, and anisotropy develops behind them with the secondary dendrite arms.See R. Glardon, W. Kurz, "Solidification path and phase diagram of directionally solidified Co-Sm-Cu alloys", J. Cryst. Growth, 51 (1981) 283-291.
