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) ; some differences could also be found in different specimens.
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.
The tiny fibers of silicon carbide
used to strengthen airplane wings and mountain bike frames just became a lot tinier.
Postle Industries introduced a vanadium-tungsten carbide
hardfacing alloy for extreme abrasion--the PS-150 Vanguard, available as an open-arc welding wire.
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.
in ductile iron castings tend to increase velocity, castings with excessive carbides
can be discerned by using an upper limit for acceptable carbide
Conditions such as galling or hot welding can be remedied by adding tantulum/niobium and titanium carbides
to the binder system.
occur when undissolved carbon combines with iron to form iron carbide
([Fe.sub.3]C), a hard and brittle phase that is not desirable in ductile iron castings.
The density of carbides
is nearly twice that of steel.
