Scope
This section specifies the method for determining the amounts of molybdenum, titanium, and vanadium in carbides of chromium, niobium, tantalum, titanium, tungsten, and vanadium, as well as mixtures of these carbides with bonding metals, and in hard alloys (including hard alloys with completely removed coatings).
This section is applicable to the determination of the amounts of molybdenum, titanium, and vanadium in carbides of chromium, niobium, tantalum, titanium, tungsten, and vanadium, as well as mixtures of these carbides with bonding metals, and in hard alloys (including hard alloys with completely removed coatings). The measurement range is 0.01% to 0.5%.
