Titanium and titanium alloys — Ti-6Al-4V — Determination of aluminium and vanadium contents — Inductively coupled plasma atomic emission spectrometric method

Scope

This document specifies an inductively coupled plasma atomic emission spectrometric method for the determination of the mass fraction of aluminium and vanadium in 6Al-4V titanium alloys.

The method is applicable to 6Al-4V titanium alloys (applicable chemical composition range other than Al and V is as follows; C: less than or equal to 0,08%, O: less than or equal to 0,20%, N: less than or equal to 0,05%, H: less than or equal to 0,0150%, Fe: less than or equal to 0,40%, each other element: less than or equal to 0,1%, total other element: less than or equal to 0,4%) with mass fraction of aluminium in the range from 4,70% to 7,00% and vanadium in the range from 3,00% to 5,00%.
