Abstract Scope |
Directed energy deposition additive manufacturing is a flexible process to fabricate parts of dissimilar materials, including functionally graded materials and metal matrix composites (MMC's). This talk will discuss some of the results from a lab-scale deposition process observed with the high-speed imaging synchrotron beamline at Argonne National Laboratory’s Advanced Photon Source. In-situ imaging of deposited particles shows how these particles incorporate into the melt pool. Deposited particles include a variety of ceramics and coated particles, which flow into a laser-induced melt pool of a titanium, aluminum or steel alloy. Results show how velocity and injection depth of these particles can influence the overall additively built part. With control and flexibility during fabrication, these new materials can exhibit greater strength, decreased density, and improved thermal properties compared to those of conventional materials. |
