Rapid Hot Pressing Sintering of Titanium Diboride/Copper Composites

Image
Ceramic particle dispersion reinforced copper matrix composites (CMC) have good electrical conductivity and mechanical properties, so they have good application prospects in the electrical and electronic industries. There are many preparation methods for CMC, and the preparation of high-performance composite materials using in-situ prepared metal matrix composite powders (MMPs) as raw materials have attracted much attention in recent years due to their comprehensive advantages. The researchers prepared in-situ spherical TiB2 p/Cu composite powders by liquid phase in-situ reaction and used them as raw materials to prepare composite materials by rapid hot pressing sintering. Then, the sintered TiB2P/Cu composites were deformed by a combination of hot rolling and cold rolling. Finally, the effect of rolling deformation on the sintered TiB2p/Cu composites was studied and discussed from the two aspects of microstructure evolution and composite performance. The relevant results were publish...

Unlocking the Potential of Silicon Carbide (SiC): Advantages in Power, Efficiency, and High-Temperature Applications

What are the main functions of titanium carbide in cemented carbide?

Image
Titanium carbide , as a hard material with excellent physical and chemical properties, plays a vital role in cemented carbide. Carbide, as an indispensable high-performance material in modern industry, is widely used in extreme working conditions such as cutting, wear, high temperature and high pressure. Its performance directly affects product quality and production efficiency. The addition of titanium carbide not only significantly improves the hardness, wear resistance, oxidation resistance and fracture toughness of cemented carbide but also improves its processing performance and high-temperature stability, paving the way for the wide application of cemented carbide in many fields. Provides a solid foundation. Titanium carbide applied in cemented carbide Improved hardness and wear resistance Titanium carbide is known for its extremely high hardness, second only to diamond, a property that makes its use in cemented carbide particularly critical. When titanium carbide is added to cem...

How Do The Crystal Structure And Unit Cell Parameters Of Boron Carbide Change Under Different High Pressures? Part

Image
Phase transition law of boron carbide under high pressure Under high pressure, the phase transition law of boron carbide is quite complicated. According to research, the phase transition of boron carbide under high pressure covers the phase transition from α-B4C to β-B4C, the phase transition from β-B4C to γ-B4C, and the decomposition of γ-B4C into B2O3 and C. If boron carbide is affected by high pressure, α-BxC will become β-BxC. If the pressure continues to increase, β-BxC will become γ-BxC. When the pressure reaches a certain value, γ-BxC will decompose into B?O? and C. In this process, the crystal structure and Raman spectral characteristics of B2O3 and C are different from those of γ-B4C. What impact will the high-pressure phase transition of boron carbide have on Raman spectroscopy? Raman spectroscopy is a particularly important method for characterizing the properties of materials. In the study of boron carbide, Raman spectroscopy is widely used to explore its structu...
