After tempering, some carbides could precipitate from martensite; consequently, the amount of C and alloyed elements decreases; hence the diffraction peak of martensite deviates to higher angle.

Effective cleaning plays a vital role in the manufacturing process as C4 Carbides Project Engineer, Simon Peckham, explains.

Chromium is uniformly distributed between carbides and solid solution, tungsten and molybdenum are bound mainly in carbides [M.sub.6]C and [M.sub.2]C, and vanadium--in MC (VC).

Testers also should keep in mind that matrix variations (ferrite, pearlite, martensite and carbide) can affect the velocity of the sound waves, as can extreme variations in alloy content (C, Si etc.).

Sound advice for nodularity testing

Sintered tungsten carbides have a thermal expansion coefficient that typically ranges from 4.5 to 8.5 x 10 -6/k from 32F to 1472F (0C to 800C)...less than half that of tool steels.
