“…Taking advantage of this idea in conjunction with the LENS™ technique, we executed high throughput (HT) processing to produce samples for this study. Previously, this technique has been used to study composition-microstructure relationships and composition-property correlations for hydrogen storage, oxidation resistance, and magnetic properties [17][18][19][20][21]. Use of elemental powder blends [22,23] avoids prealloyed powders.…”

Recent advances in additive manufacturing (AM) reveal an exciting opportunity to build materials with novel internal structures combined with intricate part geometries that cannot be achieved by traditional manufacturing approaches. The large space of potential material chemistries combined with non-equilibrium microstructures obtained in AM presents a significant challenge for a systematic exploration and optimization of the final properties exhibited by AM parts when using the existing knowledge databases established for conventionally processed materials. In this paper, we demonstrate novel high throughput assays that can be used to prototype a large library of material chemistries (and possibly different process histories) in small quantities, and subsequently apply spherical indentation stress-strain protocols to screen them for their mechanical performance. The potential of these new assays is demonstrated on a class of Ti-Ni alloys, whose Ni composition ranges between 0 and 11%wt.

“…13,14 Because the LD process creates a melt pool in the wake of the laser, the technique can be used to perform layer-by-layer alloying, where each deposited layer can have a different composition than the previous layer through the blending of different feedstock powders. This technique fundamentally changes the paradigm for the fabrication of metal hardware because it allows, for the first time, chemical composition to be used as a design parameter.…”

The current work provides an overview of the state-of-the-art in polymer and metal additive manufacturing and provides a progress report on the science and technology behind gradient metal alloys produced through laser deposition. The research discusses a road map for creating gradient metals using additive manufacturing, demonstrates basic science results obtainable through the methodology, shows examples of prototype gradient hardware, and suggests that Compositionally Graded Metals is an emerging field of metallurgy research.

“…Predictive modeling can improve and accelerate advances already being made resulting in advances in alloy performance and the development of new classes of alloys. Demonstrations of gradient compositions, gas-phase in-situ alloying, functional density gradients, and other novel constructs have already been demonstrated by additive manufacturing techniques [10,11,12]. It is likely that the pace of adoption and integration of these new materials will be severely constrained in the aerospace market by the inability to fund a largescale data allowables program.…”
