Advanced Engineering Materials, EarlyView.This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.

Journal of Materials Research and Technology, 2020 The solution and aging treatments (SAT) were adopted to improve the microstructure and the corrosion resistance ability of laser solid formed (LSFed) Ti-6Al-4 V titanium alloy. The effect of the SAT on the electrochemical properties of the LSFed Ti-6Al-4

Seismic performance analysis of Kuala Lumpur air traffic control tower by friction damper [PDF]
, 2009 In structural earthquake engineering, different kinds of energy absorption devices were invented during last 30 years (Guan et al, 2004). And more than one-decade research has shown that, on account of the virtue of no power requirement, rapid response ...

Friction on a Quantized Vortex in a Superfluid
, 1998 We obtain the explicit expression of the friction on a moving quantized vortex, following the formulation of Thouless, Ao and Niu. It is shown that the friction on a moving vortex is sensitive to details but does not change the transverse force.

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 ...

Network-Configurations of Dynamic Friction Patterns
, 2012 The complex configurations of dynamic friction patterns-regarding real time contact areas- are transformed into appropriate networks. With this transformation of a system to network space, many properties can be inferred about the structure and dynamics ...

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Static and Dry Friction due to Multiscale Surface Roughness
, 2008 It is shown on the basis of scaling arguments that a disordered interface between two elastic solids will quite generally exhibit static and "dry friction" (i.e., kinetic friction which does not vanish as the sliding velocity approaches zero), because of
