Public demand for an efficient and sustainable use of energy and resources has led to new
design criteria for technical products. An even more consequent use of light-weight …

This review presents a thorough survey of the roll bonding process with a focus on the
bimetallic bars/tubes as well as the bonding models and criteria. The review aims to provide …

Solid bonding of aluminium is an important joining technology with applications in
fabrication, forming and new low-carbon recycling routes. The influence of deformation …

In porthole die extrusion process of aluminum alloy profiles, the formation of longitudinal
weld seams (L-seams) is inevitable. Analysis of L-seam defects and investigation of solid …

In order to improve the mechanical properties of profiles extruded from aluminum chips, a
four turn equal channel angular pressing tool was integrated into an extrusion die (iECAP …

Decoupling economic growth from resource depletion is an urgent target to achieve.
Adopting circular economy paradigm is the only way to address such challenge …

This study is aimed to develop a new criterion to predict the solid-state welding quality of
magnesium alloy during the porthole die extrusion of hollow profiles. In this criterion, the …

Aluminum multi-port extrusion tube is processed by the porthole die extrusion and the
internal tube walls are welded through the solid state metallurgical bonding. In order to …

To obtain profiles with sound weld seams, the effects of extrusion parameters and heat
treatment on microstructures and mechanical properties of the weld seam were revealed. It …

A numerical model for the prediction of the wire quality produced by the novel direct
machining chip recycling technique known as Friction Stir Extrusion (FSE) is presented. Wire …
