  • Effect of Laser Powder Bed Fusion Parameters and Hot Isostatic Pressing on the Microstructure and Mechanical Properties of C22 Alloy

    Creator:
    Yan, Dongqing
    Abstract:
    A nickel-based Hastelloy C22 powder with a nominal composition of Ni-21.30Cr-13.36Mo-1.92Co-2.94W-3.85Fe-0.23Mn-0.3V(wt%) and particle size distribution of D₁₀=23.8±0.3 μm, D₅₀=37.5±0.2μm, and D₉₀=59.3±1.1 μm was gas atomized to be used as a feedstock in Laser Powder Bed Fusion (LPBF). In this study, laser power and scanning speed were optimized to manufacture specimens...

  • Selective Laser Melting of H13 Tool Steel for Rapid Tooling

    Creator:
    Katancik, Michael
    Abstract:
    The current knowledge on the microstructural evolutions and mechanical properties of selective laser melting (SLM) produced H13 tool steel components is limited. This research is focused on optimization of SLM processing parameters for H13 tool steel and investigation of microstructure and mechanical properties of H13 tool steel components after SLM...

  • Numerical and Analytical Modeling of Temperature Evolution in Laser Processing of Materials

    Creator:
    Ball, Stefan R.
    Abstract:
    The ultimate goal of this work is to analyze and compare two predictive models of thermal profile in laser processing of materials. An analytical method that uses closed-form equations to represent a geometric model of a laser heat source will be contrasted with a commercial computational fluid dynamics code that...

  • Foam-Core Meniscus Coating and Diffusion Bonding for Energy Applications

    Creator:
    Saranam, Venkata Rajesh
    Abstract:
    In the second chapter, a foam-core meniscus coating process was developed for retrofitting 100 nm-scale sol-gel anti-reflective coatings onto in-field solar panels through the deposition, evaporation, and curing of wet films.Advantages of this technique include the means to control fluid flow relative to substrate motion and the ability to conform...
