This document specifies a molecular absorption spectrophotometric method for the determination of
titanium content in nickel alloys.
The method is applicable to titanium contents between 0,3 % (mass fraction) and 5,0 % (mass fraction).
Molybdenum, if present in the alloy, can cause a high bias in the reported titanium value to the extent of
0,001 % Ti for every 1,0 % Mo.
NOTE 1 Evidence exists that extension of this method is possible for titanium contents down to 0,05 % (mass
fraction).
NOTE 2 Modifications in the general method allow the determination of titanium in alloys containing tungsten
and/or tantalum.nd edition 2020-11 Nickel alloys — Determination of titanium content — Diantipyrylmethane molecular absorption method Alliages de nickel — Détermination de la teneur en titane — Méthode par spectrophotométrie d’absorption moléculaire au diantipyrylméthane Reference number ISO 11433:2020(E) ？ ISO 2020 ISO 11433:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 20
