carbide

But at the peak temperature near the temperatures of melting, a significant amount of undissolved carbides still exist in the surface.

The methods as how to control the surface carbon concentration, carbon profiles and the morphology of carbides have been put forward.

The carbides are fractured and fragmented in form of shear fracture mainly and then dissolved and disappeared.

The application of Rare earth elements in cemented carbides has been one of the national major projects.

This process is extremely useful, therefore, in tool making, since hardened steel and carbides can be machined with easy.

The fine, equiaxed and homogeneous carbides could be obtained at the end of the first holding stage.

According to the size of carbides and the amount of exposed matrix, the annealed structure can be divided into low and high grades.

The larger carbides existing in that part also wrecked continuity of the base and accelerated the forming and expanding of the crack.

The valid controlution of carburization atmosphere during the later stage of Sintering-HIP can directly prepare gradient cemented carbides.

According to thermodynamic calculation, partial carbides can be dissolved if the alloy is treated at very high temperature.

The existence of block carbides in the matrix can retard effectively crack propagation.

moulds for metal (other than ingot moulds), metal carbides, glass, mineral materials, rubber or plastics.

Tungsten. Like molybdenum forms hard carbides which preserve the hardness of tool steels at high temperature.

Refractory metal and cemented carbides: steel, metal steel, tungsten metal, crucible etc.

The peaks of chromium and carbon show the detected positions of the chromium carbides.

The results show that the structure of the surfacing layer was martensite, carbides and residual austenite.

With the rapid developing of industry, cemented carbides is required higher and higher.

SEM observations showed that the crack initiated at carbides, microporosities and in the matrix near the microporosities.

Hardened tool steels and carbides are effectively machined with this method.

Therefore, the removal way of cemented carbides in nozzle-type ELID grinding was mainly ductile removal mode.

The results show that aluminum can refine as-cast microstructure, carbides and grain size.

The orientation control of the primary carbides in the hard layer is studied.

The exceptional tool performance of sintered carbides results from their very high hardness and high compressive strength.

The effect of adding rare earth elements, metals, metal carbides into cemented carbide, are summarized.

It is thus more supersaturated precipitation carbides can happen in mostly of ferrite grains.

The cemented carbides are prepared according to normal powder metallurgical procedures.

Such as volcanoes, carbides of metals, or simply by the reaction of carbon dioxide, water and catalysts with sunlight.

presses for working metal or metal carbides, not specified above.

The development and research status of boron carbides for the Bulletproof Ceramic were summarized in this article.

Q1: small uniform carbides in an alloy ferrite matrix.

State structure and transformation of carbides in carburized layers are analyzed by use of telescope, X-ray diffraction and energy spectrum.

the Cr-rich M7C3 carbides have the best oxidation resistance.

Thus, the application of diamond CVD is limited to materials which will not soften at this temperature such as cemented carbides.

The wear test was carried on a nozzle which was made from carbides and ceramics on high pressure abrasive water-jet machine.

Systematic experiments were made to study the cutting performance of the Re carbides as cutting tool materials.

There are two kinds of carbides with different color shades in alloys.

It is found that larger amounts of carbides such as M3C, MC and M2C and some compound inclusions of oxides and sulphides exist in the steel.
