Effect of Carbon Content on the Phase Composition, Microstructure and Mechanical Properties of the TiC Layer Formed in Hot-Pressed Titanium-Steel Composites
Autor: Marius Grad, Jan Zentgraf, Ulrich Schultheiss, Lukas Esper, Andreas Diemar, Ulf Noster, Lothar Spiess
Publikováno v: Metals, Vol 14, Iss 9, p 959 (2024)
During the hot pressing of pure titanium and different carbon steels in a temperature range of ϑ = 950–1050 °C, a compound layer up to dL≈10 μm thick is formed at the titanium–steel interface. With a higher carbon content of the used steel,

On the nanoindentation behavior of a TiC layer formed through thermo-reactive diffusion during hot pressing of Ti and cast iron
Autor: Marius Grad, Naresh Nadammal, Darius Tytko, Ulf Noster
Publikováno v: Materials Letters: X, Vol 15, Iss , Pp 100161- (2022)
Hot pressing of pure Ti and cast iron under vacuum formed a ∼15 µm wide TiC-layer through the thermo-reactive diffusion process. Nanoindentation testing of the TiC-layer revealed average hardness and elastic modulus values of ∼35 GPa and ∼400

Computational analysis of the effects of geometric irregularities and post-processing steps on the mechanical behavior of additively manufactured 316L stainless steel stents.
Autor: Lisa Wiesent, Ulrich Schultheiß, Philipp Lulla, Ulf Noster, Thomas Schratzenstaller, Christof Schmid, Aida Nonn, Ashley Spear
Publikováno v: PLoS ONE, Vol 15, Iss 12, p e0244463 (2020)
Advances in additive manufacturing enable the production of tailored lattice structures and thus, in principle, coronary stents. This study investigates the effects of process-related irregularities, heat and surface treatment on the morphology, mech

An Integrative Experimental Approach to Design Optimization and Removal Strategies of Supporting Structures Used during L-PBF of SS316L Aortic Stents
Autor: Marius Grad, Naresh Nadammal, Ulrich Schultheiss, Philipp Lulla, Ulf Noster
Publikováno v: Applied Sciences, Vol 11, Iss 19, p 9176 (2021)
One of the fundamental challenges in L-PBF of filigree geometries, such as aortic stents used in biomedical applications, is the requirement for a robust yet easily removable support structure that allows each component to be successfully fabricated

Enhancement of laser cut edge quality of ultra-thin titanium grade 2 sheets by applying in-process approach using modulated Yb:YAG continuous wave fibre laser
Autor: Moritz Burger, Alexander Bartsch, Marius Grad, Lukas Esper, Ulrich Schultheiß, Ulf Noster, Thomas Schratzenstaller
Titanium is used in many areas due to its excellent mechanical, biological and corrosion-resistant properties. Implants often have thin and filigree structures, providing an ideal application for laser fine cutting. In literature, the main focus is p

Fügepartner schlüssig zu Leichtbaukomponenten verbinden?
Autor: Ulf Noster, Robert D. Bitsche, Christian Peterlechner
Publikováno v: Lightweight Design. 1:30-34
Kombinationen aus kraft- und formschlussigen Verbindungen erhohen die Leistung bei im Hybridguss verbundenen Gussteilen mit Anbau- oder Einlegeteilen und machen separate Fugeprozesse uberflussig. Simulations-Methoden unterstutzen das Design kraft- un
