Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Foundations on sloped fills under repeated loading
, 2013 A large number of physical model tests were conducted with foundations placed on both unreinforced and reinforced sloped fills of different angles and subjected to repeated loading of different amplitudes and frequencies. Both small- and large-scale experiments were carried out under plane-strain conditions with a strip footing placed at a constant ...
