PtIr protective coating system for precision glass molding tools: design, evaluation and mechanism of degradation
Marcel Friedrichs, Zirong Peng, Tim Grunwald +3
During Precision Glass Molding (PGM), the molding tools have to withstand severe thermo-chemical and thermo-mechanical loads cyclically. To protect their high-quality optical surfa…
Atomic-scale grain boundary engineering to overcome hot-cracking in additively-manufactured superalloys
Paraskevas Kontis, Edouard Chauvet, Zirong Peng +9
There are still debates regarding the mechanisms that lead to hot cracking in parts build by additive manufacturing (AM) of non-weldable Ni-based superalloys. This lack of in-depth…
Unraveling the Metastability of C_n^{2+} (n=2-4) Clusters
Zirong Peng, David Zanuttini, Benoit Gervais +6
Pure carbon clusters have received considerable attention for a long time. However, fundamental questions such as what the smallest stable carbon cluster dication is remain unclear…
On the effect of Re addition on microstructural evolution of a CoNi-based superalloy
P. Pandey, A. K. Sawant, B. Nithin +4
In this study, the effect of rhenium (Re) addition on microstructural evolution of a new low-density Co-Ni-Al-Mo-Nb based superalloy is presented. Addition of Re significantly infl…
Reflections on the analysis of interfaces and grain boundaries by atom probe tomography
Benjamin M. Jenkins, Frédéric Danoix, Mohamed Gouné +4
Interfaces play critical roles in materials, and are usually both structurally and compositionally complex microstructural features. The precise characterization of their nature in…
