Compositionally graded alloys fabricated using the laser powder bed fusion technique by Wei, Siyuan

“…In this study, among the several available AM processes, the LPBF technique is selected to fabricate compositionally graded alloys, as it has higher spatial resolution and lower cost, compared to directed energy deposition (DED) and electron beam powder bed fusion (EBPBF). With three different LPBF setups and four alloy systems examined in this study, the following objectives are achieved: (i) screening out, from a large range of compositions, the alloys that are amenable to LPBF, (ii) examining the effects of the LPBF characteristics, e.g., rapid cooling rate, on the micro-/meso-structure and properties of the fabricated parts with varying chemical compositions, and (iii) evaluating the fabrication methods in terms of types of achieved gradation (stepwise or smooth), efficiency, and level of chemical segregation. …”

Development of schlieren-image based flow diagnostics and analysis for supersonic jet flows by Lim, Desmond Haoxiang

“…When compared against PIV results, the much higher spatial and temporal resolution of SIVOF resulted in sharper and clearer vortical structures that can be tracked across several time-resolved frames. An embedded shear layer resulting from subsonic flow downstream of a 0.9 mm diameter Mach disk was also observed, which is testament to the high-fidelity flow field offered by SIVOF. …”
