“…Ribeiro et al, Fanghänel et al, as well as Lindner and Schmitt developed integrated analytical approaches for planning process chains with regard to economic, environmental and functional performance dimensions. Modelling on a process level enables the prediction of impacts of certain process chain [153][154][155]. Le Duigou et al focus on a closed loop design methodology for metals instead, aiming at increasing the recycled aluminium content in the final part [121].…”

Lightweight structures are increasingly necessary to meet current engineering requirements. Weight reduction in diverse applications such as automobiles or machine tools is achieved either by using less material or by substituting material with a lighter one, which provides more functionality per unit of weight. To be an effective enabler for sustainability, lightweight structures should result in lower environmental impacts per functional unit when compared to conventional structures on a life cycle basis. However, applying new materials and manufacturing processes often leads to an increase in environmental impacts from the raw materials and production stage of the life cycle. Furthermore, end-of-life disassembly and recycling may become more difficult. In addition, the expected efficiency gains from the use of lightweight structures depend on how the overall market and technical systems respond to them. Consequently, the environmental evaluation of lightweight structures in engineering entails various methodological challenges. Organised around a life cycle engineering framework with a focus on eco-effectiveness, this paper provides a comprehensive review of lightweight structure applications and the challenges and opportunities they present in a life cycle engineering context.

“…The cost of parts recovery is much lower than their manufacturing cost, as recovery does not include such labor-, energy-and material-intensive processes as remelting (when recycling the worn-out item), casting, stamping and machining (when producing a new item). In many cases, the solution of these problems is facilitated by the wide use of aluminum alloys in industry, the development and introduction of resource-efficient technologies of their production, and the creation of new constructional and precision materials with pre-designed properties [5][6][7].…”

Structure–Phase Transformations in the Modified Surface of Al-20%Si Alloy Subjected to Two-Stage Treatment

et al. 2022

The paper describes the two-stage modification of the surface layer of hypereutectic Al-20%Si alloy that combines electroexplosive alloying by an Al-Y2O system with subsequent irradiation by pulsed electron beam. It is shown that irrespective of the modification mode, a multilayer structure is formed consisting of the following layers: a surface layer and an intermediate layer. The surface layer is a multiphase material, the thickness of which varies within 1 µm. The intermediate layer, the thickness of which varies within 40 µm, is made up of rapid solidification cells formed due to the rapid cooling of molten layer of Al-20%Si alloy. The cells are divided by thin interlayers mostly formed by silicon nanoparticles.
