Journal ArticleDOI
3D printing of high-strength aluminium alloys
John H. Martin,Brennan Yahata,Jacob M. Hundley,Justin Mayer,Tobias A. Schaedler,Tresa M. Pollock +5 more
TL;DR: The approach to metal-based additive manufacturing is applicable to a wide range of alloys and can be implemented using a range of additive machines, and provides a foundation for broad industrial applicability, including where electron-beam melting or directed-energy-deposition techniques are used instead of selective laser melting.
Journal ArticleDOI
Grain refinement mechanisms in additively manufactured nano-functionalized aluminum
J. Hunter Martin,Yahata Brennan D,Yahata Brennan D,Justin Mayer,Robert Mone,Ekaterina Stonkevitch,Miller Julie,M.R. O'Masta,Tobias A. Schaedler,Jacob M. Hundley,Patrick G. Callahan,Tresa M. Pollock +11 more
TL;DR: In this article, the Al-Ta system, in which Al3Ta intermetallic compounds are demonstrated to have substantial grain refining capacity, is shown to be reduced relative to pure aluminum by 1000X when tantalum is added at 1 vol%.
Journal ArticleDOI
Additive manufacturing of metal matrix composites via nanofunctionalization
John H. Martin,Brennan Yahata,Eric C. Clough,Justin Mayer,Jacob M. Hundley,Tobias A. Schaedler +5 more
TL;DR: In this article, Alloy-agnostic, nanofunctionalization process has been utilized to produce metal matrix composites (MMCs) via additive manufacturing, providing new geometric freedom for MMC design.
Journal ArticleDOI
The effect of post-synthesis aging on the ligand exchange activity of iron oxide nanoparticles
Kathleen Davis,Michael Vidmar,Airat Khasanov,Brian Cole,Melanie Ghelardini,Justin Mayer,Christopher L. Kitchens,Amar Nath,Brian A. Powell,O. Thompson Mefford +9 more
TL;DR: An increase in the total amount of ligands exchanged with aging up to 30days was revealed, and a follow-up study suggested this increase in ligand adsorption may be due to changes in the Fe2+/Fe3+ ratio on the surface as the particles aged.

Nanoparticle composite welding filler materials, and methods for producing the same
TL;DR: In this paper, a universal approach is described to produce welding filler materials with enhanced grain refining, for making welded objects with hot-crack resistance, enabling the welded object to be free of hot cracks.
