Understanding creep of a single-crystalline Co-Al-W-Ta superalloy by studying the deformation mechanism, segregation tendency and stacking fault energy
Nicklas Volz, Fei Xue, Christopher H. Zenk +9
A systematic study of the compression creep properties of a single-crystalline Co-base superalloy (Co-9Al-7.5W-2Ta) was conducted at 950 °C, 975 °C and 1000 °C to reveal the influe…
Revealing atomic-scale vacancy-solute interaction in nickel
Felipe F. Morgado, Shyam Katnagallu, Christoph Freysoldt +7
Imaging individual vacancies in solids and revealing their interactions with solute atoms remains one of the frontiers in microscopy and microanalysis. Here we study a creep-deform…
On the influence of Al-concentration on the fracture toughness of NiAl: microcantilever fracture tests and atomistic simulations
Ralf Webler, Polina N. Baranova, Shivraj Karewar +5
The mechanical properties of the stoichiometric B2 -phase of NiAl are well established, however the effect of off-stoichiometric composition on the fracture toughness has not ye…
Low temperature deformation of MoSi and the effect of Ta, Nb and Al as alloying elements
Carolin Zenk, James S. K. -L. Gibson, Verena Maier-Kiener +3
Molybdenum disilicide (MoSi) is a very promising material for high temperature structural applications due to its high melting point (2030 °C), low density, high thermal conduc…
Imaging individual solute atoms at crystalline imperfections in metals
Shyam Katnagallu, Leigh T. Stephenson, Isabelle Mouton +11
Directly imaging all atoms constituting a material and, maybe more importantly, crystalline defects that dictate materials' properties, remains a formidable challenge. Here, we pro…
New Insights into the Coupling of and Mesons to the Nucleon
M. Kirchbach, L. Tiator, S. Neumeier +1
We show that the contact couplings of neutral pseudoscalar and axial mesons to the nucleon are proportional to , the fraction of nucleon spin carried by the strange quark sea,…
