  Ultra-High-Temperature Sintering. Ultra-high-temperature sintering (UHTS) is defined as sintering ferrous powder at temperatures approaching ° F. The benefits of high-temperature sintering are augmented with UHTS. Sintered neck formation and alloy homogenization get a big boost from this new processing technique. Pages - The high temperature conditions which are conducive to sintering also cause microstructural coarsening. Differences in grain size or pore size cause small energy differences, and atomic motion responds to these differences by progressively enlarging the larger, lower energy grains while consuming the smaller, higher energy grains. An Overview of Densification, Microstructure and Mechanical Property of Additively Manufactured Ti-6Al-4V — Comparison among Selective Laser Melting, Electron Beam Melting, Laser Metal Deposition and Selective Laser Sintering, and with Conventional Powder. Cited by: 9. We developed a mathematical optimization model coupling chemical compositions and high-temperature characteristics of sintering materials, targeting the best quality and lowest cost. The simplex algorithm was adopted to solve this model. Four kinds of imported iron ores, two kinds of Chinese iron ore concentrates, and two kinds of fluxes were selected to verify both the model and the algorithm.

The rotational molding process is a high-temperature, low-pressure plastic-forming process that uses heat and biaxial rotation (i.e., angular rotation on two axes) to produce hollow, one-piece parts. Critics of the process point to its long cycle times—only one or two cycles an hour can typically occur, as opposed to other processes such as. Powder metallurgy, fabrication of metal objects from a powder rather than casting from molten metal or forging at softening temperatures. In some cases the powder method is more economical, as in fashioning small metal parts such as gears for small machines, in which casting would involve.   The grain size of sintered sample increases with increasing sintering temperature and the grain size distribution was fairly wide at especially high sintering temperature. Samples sintered at a low sintering temperature ( 0 C 0 C) showed fine (about nm) equiaxed grains under 5 GPa pressures as shown in Fig. 10 (a), (b). This book provides scientific principles, processing conditions, probable failure mechanisms, and describes reliability performance and equipment required for implementing high-temperature and lead-free die attach materials. It addresses both sintering and soldering.

The mixed carbide powders were synthesized by high‐energy ball milling (HEBM) followed by CTR at °C, which resulted in an average particle size of ~ nm and an oxygen content of wt%. Low sintering temperature, high relative densities, and fine grain sizes were achieved through the use of synthesized powders. 11th International Symposium On High Temperature Metallurgical Processing 11th International Symposium On High Temperature Metallurgical Processing by Zhiwei Peng.

Princeton, N.J.: Metal Powder Industries Federation, © The results showed that sintering temperatures were effectively decreased by increasing pressure. Under MPa, the sintering temperature for Fe, Co, Ni and Cu powders were about , , and K respectively, which were K lower than those without pressure.
