Abstract: The web-based e-learning tool “AluMATTER” is presented which can be accessed under the
address “http://aluminium.matter.org.uk” and offers a new interactive course for students, engineers
or technicians to learn all about Aluminium science and technologies. The e-learning program
fulfils all distant learning requirements and intends to supplement regular teaching courses. It
allows users to access the material in a context relevant to their own requirements and background.
Abstract: Companies and research organizations in the aluminium industry have a number of different strategies for protecting their new developments. Many research organizations have a patent focused strategy to facilitate commercialization of their new technologies. Conversely, primary aluminium producers tend to use patent protection more selectively, as they are able to use other Intellectual Property protection means such as trade secrets to protect their developments. This paper provides an overview of international patent publications from 1995 to 2008 in the field of electrolytic aluminium production and comments on perceived factors driving IP protection of these developments.

Abstract: This study presents experimental results of an approach consisting of local heating of aluminium alloy structures with the purpose of introducing a local change of material properties. Such modification can be precisely induced using a laser source, as detailed in this study. By a laser induced pre-treatment, the material properties are locally changed so that influencing the material flow is possible. It is therefore possible to improve deep drawing of high strength aluminium alloys. This technique can also be applied to thin-walled section aluminium tubes in order to act as local triggering of the deformation process reducing peak loads and inducing energy favourable folding modes. This study presents preliminary results of temperature, heating cycle and laser parameters influence in material properties and microstructure of a selected 6060-T5 aluminium alloy.

Abstract: This paper discusses the most current issues of overhead power transmission relative to the development of new conductive materials with unconventional technological and operational qualities. The present condition is based on the one hand on the traditional aluminium-steel conductors with their numerous weaknesses, and on the other hand on state of the art design solutions employing self-supporting, highly-conductive, and thermally and rheologically resistant aluminium alloys. A gap exists between pure aluminium-based conductors which are no longer sufficient and conductors made of precipitation hardened aluminium alloys, which even though they allow to achieve perfect properties, they are not sufficiently cost-effective as for their complex manufacturing technologies. For these reasons, light and sufficiently strong materials based on aluminium are needed, which enable simplified technologies for processing into conductors. Non-precipitation hardened aluminium alloys with such alloy additives as Fe, Si, Cu, Mg, Ti, B, and rare earth metals are preferred in this area. An appropriate composition of these elements, as well as manufacturing and alloy production technology (casting, rolling and drawing) create potential opportunities to obtain wires and conductors with application properties required by electrical power engineering. This paper thoroughly analyses the impact of various elements on the formation of mechanical and electrical properties of aluminium alloys.
