Residual Stresses Around Welds in Nickel-based Superalloys

Journal of Neutron Research, 2004
Welding of nickel-based superalloys is employed in the manufacture of many important components of the jet engine, such as combustor casings, compressor disc assemblies, etc. Welds induce microstructural modification in the weld seam and the heat affected zone (HAZ) which generally reduce the fatigue resistance compared to that of the parent metal ...

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

Advanced Materials Technologies, EarlyView.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

Synchrotron x-ray measurement and finite element analysis of residual strain in TIG welded aluminium alloy 2024 [PDF]

, 2006
Residual strains have been measured in a tungsten inert gas (TIG) butt-welded 2024 aluminum alloy plate using synchrotron X-ray diffraction. Novel two-dimensional strain maps spanning the entire plate reveal steep gradients in residual stress and provide

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design

Advanced Materials Technologies, EarlyView.
This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...
