sintering processing (HPS) has been considered as an effective method for producing full-dense TiB 2 ce-ramics without any additives. The main features of HPS are a low sintering temperature and high sinter-ing rate. High pressure sintering kinetics of TiB 2 powder with a mean particle diameter of 60 μm was studied earlier [6].

01.11.2018 · Compared to complex wet-chemical processes, the solid-state sintering method is simple and convenient, which can avoid secondary phase formation. More recently, the pressureless sintering (PLS) has been shown to promote the formation of homogeneous solid solutions below 1300 °C , , . The low-temperature hot press sintering (HPS) technique can make up for this disadvantage. Its …
What is Sintering and Hot pressing? - Meetyou …
The sintering process during hot pressing is a highly unbalanced process. When the mixture powder is continuously heated under pressure, the oxide film on the surface of the powder is broken under pressure and can be reduced by carbon. However, unlike the sintering process, the hot pressing does not have enough time to balance the solubility of WC in Co, and the recrystallization process through the liquid …

01.07.2016 · The HPS process was carried out in a boron nitride-coated graphite die at 1850 °C for 1 h under a uniaxial load of 20 MPa with Ar atmosphere protection. The samples were first heated to 1000 °C at a heating rate of 10 °C/min, and then to 1850 °C at 5 °C/min, at which they were kept for 1 h. Because of the limited capacity of the furnace, uniaxial load >20 MPa could not be applied. Hence, the samples …

The High Speed Sintering Process. In the HSS process, a thin layer of stone granulate, such as PA12 or TPU, is applied on to a heated building platform. An inkjet print head then moves over the entire surface of the platform and moistens the areas of the construction site with infrared light-absorbing ink, on which the prototype is to be produced. The building platform is then irradiated with infrared light. The …
Sintering - Wikipedia
Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and creating one solid piece. Because the sintering …

Spark plasma sintering - Wikipedia
Spark plasma sintering (SPS), also known as field assisted sintering technique (FAST) or pulsed electric current sintering (PECS), is a sintering technique.. The main characteristic of SPS is that the pulsed or unpulsed DC or AC current directly passes through the graphite die, as well as the powder compact, in case of conductive samples. Joule heating has been found to play a dominant role in ...
