Transient dynamics of powder spattering in laser powder bed fusion additive manufacturing process revealed by in-situ high-speed high-energy x-ray imaging

Journal Article Guo, Qilin ; Zhao, Cang ; Escano, Luis I. ; ... - Acta Materialia

Powder spattering is a major cause of defect formation and quality uncertainty in the laser powder bed fusion (LPBF) additive manufacturing (AM) process. It is very difficult to investigate this with either conventional characterization tools or modeling and simulation. The detailed dynamics of powder spattering in the LPBF are still not fully understood. Here, we report insights into the transient dynamics of powder spattering in the LPBF process that were observed with in-situ high-speed high-energy x-ray imaging. Powder motion dynamics, as functions of time, environment pressure, and location, are presented. The moving speed, acceleration, and driving force of powder motionmore »« less

Fundamental studies of shock-wave-induced degradation of superconductivity in explosively fabricated, bulk, metal-matrix, copper oxide, high-temperature superconductors

Miscellaneous Niou, Chornyg-Shyr

Explosive fabrication involves the simultaneous consolidation and encapsulation of superconducting powders within a metal-matrix monolith. However, the residual superconducting properties are found to be degraded as a result of the shock-wave pressure effect. In this study shock pressure varying from 4 GPa to 19 GPa revealed that the degradation of superconductivity increased with increasing peak pressures, and exhibited a steep increase in normal-state resistance (resistance-temperature or R-T curve) and broad superconducting resistance transitions, with decreasing critical temperature. Complete recovery of superconductivity could be achieved for all shock-loaded or explosively fabricated Y-Ba-Cu-O materials above 930[degree] C, and above 860[degree] C formore »« less

Time-resolved imaging of material response during laser-induced bulk damage in SiO2

Conference Demos, S G ; Negres, R A

We report on time resolved imaging of the dynamic events taking place during laser-induced damage in the bulk of fused silica samples with nanosecond temporal resolution and one micron spatial resolution. These events include: shock/pressure wave formation and propagation, transient absorption, crack propagation and formation of residual stress fields. The work has been performed using a time-resolved microscope system that utilizes a probe pulse to acquire images at delay times covering the entire timeline of a damage event. Image information is enhanced using polarized illumination and simultaneously recording the two orthogonal polarization image components. For the case of fused silica,more »« less
