Synthesis and Sintering of Ti3SiC2–SiC Composites through Reactive Hot-Pressing of TiC and Si Precursors
MAX phases are an attractive class of layered solids that have recently attracted a great deal of attention due to their unusual and unique composition. The ternary compound Ti3SiC2 is an example of a material that combines the properties of ceramics and metals. As a ceramic, they are high stiff. Some of them are resistant to oxidation, creep, fatigue, corrosion. They are extremely refractory a...
متن کاملStrength and Toughness of Ceramic-metal Prepared by Reactive Hot Pressing Composites
William G. Fahrenholtz o 9m Ceramic Engineering Department ‘so University of Missouri-Rolls w~!!l Rolls, MO 65409 + <. +# Metal-reinforced Alz03-matrix composites were prepared using reactive hot pressing. The volume fraction of the reinforcing phase was controlled by the stoichiometry of the particular displacement reaction used. Dense Alz03-Ni and Al@3-N’b composites were fabricated using thi...
متن کاملHigh-strength zirconium diboride-based ceramic composites consolidated by low-temperature hot pressing.
Two compositions of ZrB2-based ceramic composites containing Si3N4, Al2O3 and Y2O3 have been hot-pressed at different temperatures between 1673 and 1773 K for 60 min in vacuum. The densification behavior of the composites was examined during the sintering process. The microstructures of the composites were characterized by scanning electron microscopy, and the crystalline phases were identified...
متن کاملStudy of Mechanical Properties for the Aluminum Bronze Matrix Composites of Hot Pressing
The aluminum bronze matrix alumina composites using hot press and resin infiltration were investigated to study their porosities, hardness, bending strengths, and microstructures. The experiment results show that the hardness of the sintered composites with the decrease of porosity increases. The composites without and with resin infiltration have about HRF 42-61 of about 34-40% of porosity and...
متن کاملRapid consolidation of powdered materials by induction hot pressing.
A rapid hot press system in which the heat is supplied by RF induction to rapidly consolidate thermoelectric materials is described. Use of RF induction heating enables rapid heating and consolidation of powdered materials over a wide temperature range. Such rapid consolidation in nanomaterials is typically performed by spark plasma sintering (SPS) which can be much more expensive. Details of t...
