متن کاملSurface Contamination of Alumina Ceramics by Carbon
Article history: Received: 01.05.2016. Received in revised form: 25.07.2016. Accepted: 06.09.2016. This study presents the results of investigating the cause of contamination of aluminum oxide ceramics (Al2O3) in the form of brown colored stain. Contaminated ceramic surfaces were examined with the scanning electron microscope (SEM) equipped with the Energy Dispersive Spectrometer (EDS). The res...
متن کاملSystematical Characterization of Material Response to Microscale Laser Shock Peening
The response of materials after microscale laser shock peening (mLSP) was experimentally characterized and compared with the theoretical prediction from FEM analysis in microlength level. Since mLSP is predominantly a mechanical process instead of a thermal process, the characterization focuses on mechanical properties and associated microstructures. An X-ray microdiffraction technique was appl...
متن کاملCharacterization of Plastic Deformation Induced by Microscale Laser Shock Peening
Electron backscatter diffraction (EBSD) is used to investigate crystal lattice rotation caused by plastic deformation during high-strain rate laser shock peening in single crystal aluminum and copper sample on ~11̄0! and (001) surfaces. New experimental methodologies are employed which enable measurement of the in-plane lattice rotation under approximate plane-strain conditions. Crystal lattice ...
متن کاملMassive parallel laser shock peening: Simulation, analysis, and validation
Laser shock peening (LSP) is a transient process with laser pulse duration time on the order of 10 ns, real time in situ measurement of laser/material interaction is very challenging. LSP is usually performed in a massively parallel mode to induce uniform compressive residual stress across the entire surface of the workpiece. The purpose of this paper is to investigate the effects of parallel m...
