- Metal additive manufacturing (am) offers new opportunities to enhance component performance by customizing parts for their relevant use cases. with layer-by-layer printing of complex parts, am can create functionally graded materials (fgms) that continuously transform from one element to another – generating regionally-varied properties fit to the functional requirements. despite its immense opportunity, metal am’s implementation is limited by the significant performance variability due to the rapidly evolving harsh environments that transform and degrade materials in ways that we struggle to control. fundamental studies reveal complex multi-physics trends that are difficult to reconcile, but for the full versatility of lpbf to be exploited, we require new operando x-ray diagnostics. this ssaa project is developing a new class of operando multiscale x-ray microscopes to directly map critical science required for reliable metal-am – focusing on laser powder bed fusion (lpbf). the previous ssaa award developed the first nanoscale operando imaging of lpbf and directly revealed defect formation mechanisms not previously understood.
the objective of the present proposal is to use and develop the novel microscopes to study
the alloy mixing behaviors of in-situ alloying required for fgms. the novel nano- and microscale microscopes will quantify the initial driving forces for al-cu mixing dynamics originating from a mixture of pure elemental powders. they will then directly measure the 3d flow dynamics in-situ for the first time by developing the operando limited view tomography (lvt) of lpbf. by establishing a suite of time-resolved 2d and 3d x-ray microscopes with analysis methods to track statistical dynamics, the new experimental “toolbox” will connect the complex multi-phase dynamics native to the extreme conditions of lpbf to solve open challenges for fgms.

- Metal additive manufacturing (am) is revolutionizing industry. metal am enables opportunities to enhance the performance and efficiency of components by customizing them to relevant use cases. today, metal am is used to build parts that were previously inaccessible in industry, but its implementation is limited by the significant variability in performance of the resulting components. unlike classical metallurgical processes, metal am imposes rapidly evolving harsh environments that transform and degrade materials in ways that we struggle to predict and control. fundamental studies of the deleterious defects that degrade performance have given key insights at the macroscale, but to control properties we must extend this to the multiscale picture. at the nanoscale, we understand that hierarchical structures of defects originate at the lattice level and pack into 3d hierarchical structures that govern strength, failure, fatigue, etc. our project will develop a new class of operando nanoscopic x-ray imaging methods to directly map the onset of defects in metal-am – focusing on laser powder bed fusion (lpbf). by building a suite of time-resolved 2d and 3d x-ray microscopes with analysis methods to track the statistical behaviors we resolve, we will build a new experimental “toolbox” that connects defects to the complex multiphase dynamics native to lpbf.
