The deposition of new alloy to replace a worn or damaged surface layer is common strategy for repairing remanufacturing structural components. For high-performance aluminum alloys in the automotive, aerospace, and defense industries, however, traditional fusion-based methods can lead solidification cracking, void formation, loss strength heat-affected zone. Solid-state methods, such as additive...

Biefeld-Brown effect (B-B for short) refers to the phenomenon that when a high voltage is applied an asymmetric capacitor, capacitor generates additional force. In order explore influencing factors and series characteristics of B-B wire-plate capacitors in atmospheric pressure, set experimental devices with adjustable parameters was designed. Based on this device, effects different lengths, pow...

In this paper, we present a multiple mode sensing methodology to detect active corrosion in aluminum structure utilizing the broadband piezoelectric wafer active sensors. This method uses ultrasonic Lamb wave complemented with the electromechanical impedance measurement to detect, quantify, and localize the corrosion progression in plate-like structures. The ultimate objective of this research ...

Interrupted in situ tests at high temperature characterized with X-ray microtomography were employed to study porosity evolution under loading conditions representative of aluminum hot rolling. Coupling digital volume correlation and simulations, it is possible access, for each pore, its morphological evolution, the mechanical fields experienced. The closure kinetics hundreds pores studied, whi...
