Before And After

As a result of the combination of the processes of selfpropagating high-temperature synthesis (SHS) and shear high-temperature deformation, realized in the method of SHS-extrusion, ceramic rods based on Al2O3‒SiC‒TiB2 were obtained. The influence of technological parameters of the process (delay time, pressing pressure) on the length of the obtained rods has been studied. The obtained materials were annealed in the range 1000‒1300 °C, and the microstructure and phase composition of the materials were studied before and after heat treatment.

High Temperature Synthesis

The possibility of producing hollow ceramic rods from an Al2O3-based material by SHS extrusion was first shown. A mechanism of formation of such rods by die swell was proposed. It was demonstrated that, at high temperatures, the material can have viscoelastic properties. The studies were performed in the system 2B2O3-6Al-2Cr2O3, in which a ceramic material based on aluminum and chromium oxides with strengthening chromium boride particles forms by self-propagating high temperature synthesis and redox reactions.

The aim of this work is the preparation and study of the mechanisms of structure formation of dense ceramics based on the TiC–TiB2–MeO system obtained by pressure–assisted Self-propagating High-temperature Synthesis. SHS systems were selected on the basis of thermodynamic analysis as suitable to realise regimes of synthesis with formation of liquid phase allowing a full densification. It was observed that at the adiabatic temperature the liquid phase formed in the SHS products consists of either melted oxides or eutectic TiC–TiB2. The results of microstructural observations and mechanical characterization confirm that the metal oxides effectively promote the densification of the final products and the grain refinement of the SHSproduced ceramic materials.

Mechanical And Service Properties

The self-propagating high-temperature synthesis (SHS) was used to obtain the heat-resistant porous permeable metal-ceramic material (PPMM) on base of the mixture composed of the alloyed steel's scale powder and the oxides of both metals and complex ore (monazite). The prepared SHS-material can be used as the catalytic agent for the diesel's exhaust gas purifcation. However, instead of the expensive rare-earth elements (REE) cerium and thorium the ground complex ores containing these REE can be used. The influence of the monazite's content up to 18 wt. percents on the physical, mechanical and service properties of the prepared materials were regarded in the article.Ill.8. Ref. 17. Tab. 2.
