Abstract. Tungsten carbide, known for its high hardness and brittleness, presents a challenge in traditional processes due to severe tool wear and shortened tool …

Tungsten has a melting point of 6,192°F (3,422°C) while tungsten carbide has a much higher melting point of up to 7,400°F (4,072°C). This makes it ideal for withstanding high temperatures and prevents it from losing its form or shape as easily as tungsten under high-temperature processes .

Tungsten Carbide (WC) with 0, 2, 5, 8, and 10 (by weight %) were dispersed in the matrix. The effects of WC content on the densification mechanism, …

To analyze the effect of WC powders on cemented tungsten carbide substrates, two of the above powder samples (Powder A and B) were selected for further preparations of substrates which would be used to produce metal cutting tools. Powder A and B are respectively produced at 1500 °C and 1550 °C, and the carbonization time is …

These solutions have similar normalized band gaps, which are 71.58%, 78.47% and 70.47% corresponding to tungsten carbide volume fractions 0.4374, 0.5015 and 0.4237, respectively. Figure 3 ...

On account of the reason above, considerable studies have paid overwhelming attention to the development of BTC. As pioneered by Kanemitsu [] in 1982, BTC, also named binderless cemented carbide, is tungsten carbide free of any metallic binder including cobalt, iron, and nickel.As shown in Fig. 1, because of the absence of …

Melting point of Tungsten Carbide is 2867 °C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition ...

Tungsten is a chemical element with the atomic number 74 and symbol W. It is a dense, grayish-white metal that is extremely hard. Tungsten has the highest melting point and boiling point. Tungsten is a hard metal that ranks between 7.5 and 8 on the Mohs hardness scale. However, tungsten carbide is much harder than tungsten.

Tungsten already has a large elastic modulus, one larger than most steels; tungsten carbide has an even greater elastic modulus, showing its impressive rigidity. Generally, materials stiffness correlates with a large elastic modulus, and the values shown in Table 1 prove why tungsten carbide is second only to diamond in elastic resilience.
