The drop-in carbides can be retrofitted into existing VSI crushers from KPI.
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).
Etching showed a pearlitic matrix with some small retained carbides. The edge of the plate showed the effects of very rapid cooling and solidification with fine Type D graphite with massive carbides in a pearlitic matrix.
The primary failure mode in the cleaner material was a combination of inclusion and carbide based.
High-temperature corrosion/oxidation has been shown to be a major contributor to the wear of tungsten carbide when machining medium density fiber-board (MDF) (Stewart 1992).
This is particularly true with those grades of cemented carbides with higher cobalt contents.
In addition to silicon carbide, the researchers produced titanium, niobium, iron, and boron carbide rods, reports Charles M.
All these carbide types are used in hard facing, where the proportion and type of the various carbides has a decisive influence on the overall properties of the applied facings (Fig.
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.).
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.
