Non-destructive determination of niobium in steel by neutron activation followed by X-ray spectrometry
- 36 Downloads
Neutron activation followed by X-ray spectrometry and magnetic deflection of interfering β particles is applied to the non-destructive determination of niobium in steels. AMS 5643 (17-4PH) and B.C.S. No. 320–330 steel samples containing Nb in the range of 0.02–0.3% were analyzed. By using Nb2O5 in cellulose as standard, an overall error of ±20% was obtained.
