The focus of this paper is set on technical achievements and challenges - however, these are most often closely linked to economical or ecological targets set by customers or society. Ideally, an alloy or process optimization leads to improved properties, reduced cost, and reduced emissions. With a continuously growing understanding of the underlying materials science, supported by novel computer simulation, improved alloys and processing routes have been developed. Many of the recent improvements were related to the thermal-mechanical treatment of high strength alloys for enhanced light weight design. Currently and in the future, the focus will be on sustainable development along the entire process chain, with special attention to the recycling of used products and high recycled content in new products. The optimized utilization of resources (e.g. materials, energy, etc.) will require the close cooperation of materials suppliers, product designers and manufacturers as well as R&D facilities to reconsider given material specifications and processing routes. © (2013) Trans Tech Publications, Switzerland.

In this study the artificial aging behavior of the Al-Mg-Si alloy AA 6061 was investigated in the temperature range 150-250 °C using atom probe tomography, hardness and resistivity measurements for various thermal histories. It was found that the precipitation kinetics and age-hardening response of artificial aging at temperatures below 210 °C are lowered by prior natural aging but enhanced above this temperature. An analysis of hardness data was used to evaluate the temperature dependence of precipitation kinetics and dissolution processes. Supported by theoretical considerations, it is assumed that artificial aging of Al-Mg-Si alloys is controlled via the concentration of mobile vacancies. The "vacancy-prison mechanism" proposed determines the mobile vacancy concentration in the case of natural pre-aging by temperature-dependent dissolution of co-clusters and solute-vacancy interactions. © 2011 Acta Materialia Inc.

By bringing together 21 partners including 7 major carmakers, 7 major suppliers, 2 SMEs and 5 academia / research centres, ALIVE will develop directly exploitable knowledge on materials and design concepts which offer a high potential for significantly reducing the weight of vehicles for affordable application to high productions volumes, focusing on next generation Electric Vehicles (EVs). Specifically ALIVE has set a target of achieving a 30% \ 20% weight reduction for the untrimmed vehicle body together with a 25-30% weight reduction of the hang-on parts, chassis and main interior sub-systems. ALIVE strives to generate substantial, tangible innovation in terms of vehicle design, materials, forming & joining technologies, simulation & testing and includes an exceptionally ambitious physical validation activity that will not only deliver a full structural demonstrator of all modules addressed but which will also include destructive crash and durability testing executed on the assembled modules including the entire body. The objective of the car manufacturers and the supply chain within the ALIVE consortium is to accelerate the take up of these innovative technologies, enabling their application in high volume EV production some 5 years earlier than would have been the case otherwise. Importantly the aim is to jointly exploit the potential economies of scale which can only be achieved via pre-competitive collaborative research by identifying and applying common solutions in terms of materials and their respective process technologies. ALIVE is directly linked to a network of recently concluded, on-going and planned parallel activities and as such offers a coordinated platform within the context of the Green Car program for achieving an unprecedented level of impact with respect to increasing EU competitiveness through the development and uptake of real innovation.
