Outgassing of hydrogen from a stainless steel vacuum chamber
Sefer Avdiaj, Bojan Erjavec
Izvirni znanstveni članek
Oznake: hydrogen outgassing;stainless steel;dimensionless time;pressure-rise method;throughput method;gas-flow calibration coefficient;
Due to outgassing from the walls of vacuum calibration chambers, the generation of the calibration pressure in primary vacuum calibration systems operating below 10[sup]{-6} Pa becomes un-accurate. Austenitic stainless steel (SS) is the most common construction material for ultrahigh vacuum (UHV) an ...

Oxygen diffusion in the non-evaporable getter St 707 during heat treatment
Sefer Avdiaj, Barbara Šetina, Janez Šetina, Bojan Erjavec
Izvirni znanstveni članek
Oznake: diffusion;oxidation layer;getter;zirconium;Laves phase;
The oxygen diffusion and microstructure were investigated in specimens of commercial Non Evaporable Getter under the trademark of St 707, which is an alloy of Zr(70)-V(24.6)-Fe(5.4) using EDS, AES and XRD. Specimens were in the form of tablets compressed from St 707 powder of typical particle size f ...
