Journal ArticleDOI
Steels in additive manufacturing: A review of their microstructure and properties
Priyanshu Bajaj,Avinash Hariharan,Anoop Kini,Philipp Kürnsteiner,Dierk Raabe,Eric Aimé Jägle +5 more
TL;DR: In this paper, an overview of the different kinds of steels in use in fusion-based AM processes and present their microstructures, their mechanical and corrosion properties, their heat treatments and their intended applications.
Journal ArticleDOI
Misorientation-dependent solute enrichment at interfaces and its contribution to defect formation mechanisms during laser additive manufacturing of superalloys
Avinash Hariharan,Lin Lu,Jeroen Risse,Aleksander Kostka,Baptiste Gault,Baptiste Gault,Eric Aimé Jägle,Dierk Raabe +7 more
TL;DR: In this paper, the authors used atom probe tomography coupled with transmission Kikuchi diffraction to determine the misorientation and chemical composition profiles across HAGBs (with and without cracks) and across crack-free low angle grain boundaries (LAGBs), showing that the Gibbsian interfacial excess of solutes (mainly B, C, Si, and Zr) is at least two times higher at the HAGB compared to the LAGB.
Journal ArticleDOI
Designing the microstructural constituents of an additively manufactured near β Ti alloy for an enhanced mechanical and corrosion response
Avinash Hariharan,Phil Goldberg,Tobias Gustmann,E. Maawad,Stefan Pilz,Frederic Schell,Tim Kunze,Christoph Zwahr,Annett Gebert +8 more
TL;DR: In this article , the authors investigated a wide range of LPBF parameter space to optimize the volumetric energy density, surface characteristics and melt track widths to achieve a stable process and part density of greater than 99 %.
Journal ArticleDOI
Fabrication of four-level hierarchical topographies through the combination of LIPSS and direct laser interference pattering on near-beta titanium alloy
Frederic Schell,Sabri Alamri,Avinash Hariharan,Annett Gebert,Andrés Fabián Lasagni,Andrés Fabián Lasagni,Tim Kunze +6 more
TL;DR: In this paper, complex repetitive periodic surface patterns were produced on a near-beta Ti-13Nb-13Zr alloy, using two-beam Direct Laser Interference Patterning (DLIP) employing a picosecond-pulsed laser source with wavelengths of 355 nm, 532 nm and 1064 nm.
Journal ArticleDOI
Novel low modulus beta-type Ti-Nb alloys by gallium and copper minor additions for antibacterial implant applications
Ludovico Andrea Alberta,Jithin Vishnu,Avinash Hariharan,Stefan Pilz,Annett Gebert,Mariana Calin +5 more
TL;DR: In this article , a low-modulus, corrosion-resistant Ti-based alloys with enhanced antimicrobial properties for bone-related implant applications were developed by a two-step casting process followed by homogenization treatment.
