v3.3.4
Third minutes for HeRHEA (14th November,2024):
Two new postdoctorals from IJC and CEMHTI group
Guanying report her modelling results.
To do: check the little amount V in WV by modelling.
Marie-France
PIMAT (Plasma irradiation in Materials) check the device ,first test
Zhehao visit in 10-20 December
W,WV,WNbV samples 300 nm layer grow on MgO substrates, do experiments in CEMHTI
(Summary: AFM on He exposed single crystal,A new device to control ion density in plasma, work plan for Zhehao’s visit)
Questions: Delivery of HEA, cutting in France, who pays?
(VTT is responsible for the Finfusion. Tomi will check the financial. Final meeting will be in the France(at least 2 days).)
VTT Tomi:
W WTa WMo WTaMo WV(not sure the V, how much,homogenous?)
Cut and check the microstructure
Quantity of different materials
1cm, Marie-France(at most 1mm) Aurelie: 7*7 *0.5 mm
VTT cut the sample to small piece and delivery to France. Marie-France
will polish the sample in her lab. What technical skill to check the V?
Aurelie
Task: observing the bubbles nucleation and growth by in situ ion TEM
W, WMo, WTa, WV
WTaCrV thin film, 200keV He+ at RT (Publication,)
Future work: prepare TEM thin foils?Ex situ + in situ TEM? Analyze the data.
Marie-France asks Tomi can they do annealing?
Zhehao
FCC Cantor HEA, annealing, Temp above 873K, (3D:large He bubbles, HEA:small, Steel:small and large)
HEA has small size He clusters(Binding energy in V-containing materials goes down with the increase of He atoms). At least this is good for the mechanical properties.
Flyura:
DDL for annual report 12th December, template (what information we are looking for?) Set next month in another February.
