The present work deals with aspects related to the solidification and properties of an Al-Si10Mg/SiC 20p alloy cast in plaster moulds. Several strategies were followed to shorten its solidification time such as embedding copper tubes into the mould to make circulate cooling fluids immediately after the casting step. The analysis of cooling curves provided valuable information on the effect of the particles on solidification events. The precipitation of different phases of the MMC takes place at higher temperatures and earlier than in the case of the non reinforced alloy. Particles affect the solidification pattern of the alloy and play a noticeable role in the precipitation of the phases. This fact should be taken into account to design the filling and feeding systems correctly and for modelling and processing parameters as well as in thermal treatments. Eventually samples were obtained under the highest solidification rate conditions to analyse the microstructure and tensile properties of the MMC material. Source

The EFONET CA addresses Task 9.2.1 Energy foresight network. It primarily aims at providing policy relevant input to the EC, notably in relation with the Review of the EU Energy Strategy, the establishment of the Strategic Technology Plan, the implementation of the Action Plan for Energy Efficiency. EFONET will establish and run a discussion platform gathering representatives from the research community and from all relevant stakeholder groups. It features 5 Thematic WPs, each concentrating on one of the main priorities that have already been identified within the energy foresight network established and run by the EC since 2005: methodological approaches and tools for foresight, end-use energy efficiency, foresight in the transport sector, technologies integration scenarios, barriers to the penetration of future technologies. 2 additional WPs deal with project management, network coordination and dissemination. 18 workshops and a final conference will be organised over 2.5 years, with an overall attendance estimated in some 500 participants. The main outputs are (i) country reports summarising state of the art on energy foresight methods and their application (ii) evaluation papers and policy briefs including recommendations for future energy policy formulation and implementation. EFONET aims at becoming a privileged discussion forum on future EU energy policies. To this end, provisions are made to (i) continuously extend network participation (ii) establish and maintain links with other EU energy RTD projects including those emerging for other Tasks in this call (iii) develop a dedicated interactive website to ensure wide dissemination and consolidate a virtual EFONET community that can extend beyond the contractual EFONET lifetime. The EFONET team includes 14 partners and a large group of external experts, covering 19 different countries, representing public and private research, national and EU institutions, industry, international organisations and NGOs.

The ASE-TB project will design, manufacture and tune an innovative and smart Test Bench for linear actuators that will be capable of conducting synchronized tests on two linear actuators of the same type while applying different loads on them. The test bench will also include a thermal chamber for conducting tests at regulated temperatures with one of the actuators. This actuator test bench will be based on a modular, eco-efficient and adaptive concept by integrating easily exchangeable hydraulic and mechanical components with sensors and control strategies that will allow automatic and autonomous safety controls as well as energy saving approaches that will assure optimised lifecycle costs and environmental impacts during endurance tests. This innovative concept of actuator test bench will mean thus a positive impact on the safety and working conditions of the end users of the Test Bench as well as a reduction in the time and costs associated to testing linear actuators together with an increase in the quality and reliability of said tests.

To develop adequate and well accepted security for mass transportation in Europe and the citizens affected by it, is a formidable task. The malicious threats, particularly those posed by terrorists, require a comprehensive approach: if security improvements are patchy, perpetrators are likely to find the loopholes left. With their open access points and interconnections, surface mass transportation systems are highly vulnerable, while it is technically and economically, impossible for the multiple operators to employ security measures similar to those used at airports. With eight technology and security analysis RTOs, four transportation industries and system integrators and two transportation consultancies many with previous experience of working together in projects like SeNTRE and STACCATO DEMASST is exceptionally well prepared to take on the dual challenges of analysis and networking necessary to define and achieve commitment for the strategic roadmap for the Phase 2 Demonstration project. DEMASST will develop a highly structured approach to the demonstration programme built on identifying the main security gaps and the most promising integrated solutions, utilising sufficiently mature technologies, for filling them. In the type of Concept Development & Experimentation approach proposed the experiments must be designed and analysed so as to be maximally informative. Given the vast variation in mass transportation systems an effective demonstration programme must also identify synergies between demo tasks and use less costly methods than full scale demonstration whenever that helps a broader awareness. DEMASST proposes to build the methodological infrastructure for this. But an optimal demo project design does not stop with finding scientific answers: the issue of turning demonstration into innovation is top on DEMASSTs agenda. And this approach will have utility also beyond transportation.

The paper describes the influence of 5wt % titanium diboride (TiB 2) particles on the microstructure of an Al-Cu alloy produced by plaster casting process. The elaboration route leads to a composite material with 1% of in situ TiB2 particles and 4% ex situ of TiB2 particles. The comparison of the reinforced alloy with the corresponding non-reinforced counterpart makes clear that the presence of TiB2 particles has a large influence in the observed microstructure. The presence of TiB2 particles decreases the grain sizes and the porosity level. It is also found that TiB2 particles play an important role in the precipitation events of Al2Cu precipitates that are formed during solidification at the TiB2/aluminum matrix interfaces. © 2010 WILEY-VCH Verlag GmbH & Co.
