Název v původním jazyce

Detecting porosity of 3D printed ti6al4v by nonlinear elastic wave spectroscopy

Popis výsledku v původním jazyce

Selective Electron Beam Melting (SEBM) is a powder bed technology for the production of metallic parts. In order to achieve nominal mechanical properties, microstructural defects have to bendetected and avoided. The porous microstructure can contain voids, weak bonds, sharp interfaces and loose particles, all of which was linked with the occurrence of nonlinear elastic wavenpropagation. A set of Ti-6Al-4V samples with defined internal volume with porosity ranging from 0.2 % to 20 % is experimentally investigated. An Impact Modulation Spectroscopy experiment wasnperformed on the sample set and experimental results were analysed for linear and nonlinear indicators of material porosity. Porosity was indicated by means of Resonant UltrasoundnSpectroscopy and its nonlinear counterpart, by a measure of attenuation and by nonlinear modulation.
