Journal ArticleDOI
Functionally graded material of 304L stainless steel and inconel 625 fabricated by directed energy deposition: Characterization and thermodynamic modeling
Beth E. Carroll,Richard Otis,John Paul Borgonia,J. O. Suh,R. Peter Dillon,Andrew A. Shapiro,Douglas C. Hofmann,Zi Kui Liu,Allison M. Beese +8 more
TL;DR: In this paper, a component built from 304L stainless steel incrementally graded to Inconel 625 was characterized by microscopy, chemistry, phase composition, and microhardness as a function of position.
Journal ArticleDOI
Additive manufacturing of a functionally graded material from Ti-6Al-4V to Invar: Experimental characterization and thermodynamic calculations
Lourdes D. Bobbio,Richard Otis,John Paul Borgonia,R. Peter Dillon,Andrew A. Shapiro,Zi Kui Liu,Allison M. Beese +6 more
TL;DR: In this article, the microstructure, composition, phases, and microhardness were determined as a function of position within a functionally graded materials (FGMs), and detrimental phases associated with the compositional blending of the Ti-6Al-4V and Invar formed, leading to cracking in the final part.
Developing Gradient Metal Alloys through Radial Deposition Additive
Manufacturing C. Hofmann,Scott N. Roberts,Richard Otis,Joanna Kolodziejska,R. Peter Dillon,J. O. Suh,Andrew A. Shapiro,Zi Kui Liu,John-Paul Borgonia +8 more
TL;DR: In this paper, a roadmap for developing gradient alloys is presented that uses multi-component phase diagrams as maps for composition selection so as to avoid unwanted phases, and practical applications for the new technology are demonstrated in low-coefficient of thermal expansion radially graded metal inserts for carbon-fiber spacecraft panels.
