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.
