ACMiN Seminar: Materials for application in Fusion Reactors: Determining the elastic properties of single grains in the ultrafine-grained W-Cr composite
It is our pleasure to invite you to attend the ACMiN Seminar which will be held on Thursday, April 7th at 2.00 p.m. in the ACMiN auditorium no.: 1.02A, on the second floor, bldg. D-16 (Kawiory Street 30). Alternatively you can join the meeting via the link: https://upelagh2.clickmeeting.com/acmin-seminar
The lecture entitled: „Materials for application in Fusion Reactors: Determining the elastic properties of single grains in the ultrafine-grained W-Cr composite” will be given by dr Andrzej Kądzielawa (IT4Innovations, VŠB – Technical University of Ostrava, Czech Republic; Institute of Physics Jagiellonian University, Kraków, Poland).
While the elastic properties of a composite microstructure are relatively straightforward in obtaining (e.g., using the resonance ultrasound spectroscopy), the features of a single grain are not directly measured. Here, we show our approach to determining these properties by employing large-scale ab-initio modeling techniques. Furthermore, we quantitatively reproduce the observed values of the whole microstructure, basing our model-grain compositions on the X-ray diffraction patterns, thus substantiating the utility of this procedure in the design of novel alloys.
