The new carbides cut replacement time to around 20 percent of what it is with other solutions."
The phases of the HCCI mainly consist of martensite, retained austenite, and chromium carbides of [M.sub.7][C.sub.3] (PDF: 17-0333) and [M.sub.23][C.sub.6] (PDF: 5-0721) [14]; some differences could also be found in different specimens.
C4 Carbides manufactures carbide tipped power tool accessories including jig and industrial band saw blades, which are exported across the globe.
Results of X-ray microspectral analysis and data of scanning microscopy, obtained in the <<phase contrast>> mode in backscattered electrons (BEI), confirmed presence in the structure of cast steel R6M5 (EBCHR) of carbides [M.sub.6]C, [M.sub.2]C, MC, and disperse secondary carbides, uniformly distributed within grain volume (Figure 4).
4) shows a dramatic reduction in hardness, which would indicate a corresponding reduction in unwanted carbides and an increase in ductility.
So with carbides, the objective should be to achieve uniform distribution in the matrix of smaller particles in the material.
A cryogenic treatment (-306[degrees] F) was applied to C2 tungsten carbide (WC -6% Co) and compared with untreated carbide to determine if tool wear could be reduced during turning tests with medium density fiberboard (MDF).
A new phenomenon was introduced with the development of the cemented carbides, again making higher speeds possible.

According to the desired hardness and strength of the cemented carbides, the grains of the added tungsten carbide vary in shape and size--from 0.2 [micro]m to around 20 [micro]m.
Because carbides in ductile iron castings tend to increase velocity, castings with excessive carbides can be discerned by using an upper limit for acceptable carbide levels.
Conditions such as galling or hot welding can be remedied by adding tantulum/niobium and titanium carbides to the binder system.
