In situ processing of TiB2/TiC ceramic composites by thermal explosion under pressure: experimental study and modeling

Microstructure Evolution and Model Analysis of Al2O3/ZrO2 Hypoeutectic Ceramic During Rapid Solidification

“…Once encounter the cool substrates, the high-temperature melt can be solidified quickly. Compared to the traditional rapid quenching method 16 , it has the advantages of simplifying process and saving cost and energy 17,18 . Moreover, this method can reach super high temperatures to realize rapid solidification of the system without any special crucible or extra heating device.…”

Preparation of TiC-TiB<SUB>2</SUB>-SiC Ternary Eutectic Composites by Arc-Melting and Their Characterizations

“…[4][5][6][7] Titanium carbide is an engineering material with five independent slip systems allowing the material to be ductile above 1000 K. That is also an useful characteristic as an additive material to improve the performance of SiC and/or TiB 2 -based composites. [8][9][10][11][12][13][14][15] Therefore, TiC-TiB 2 -SiC system composites could be an excellent material due to several combined properties of SiC, TiC and TiB 2 such as high hardness and high thermal conductivity.…”

Thermal Explosion Reaction in the Ti-C System under Air Atmosphere

“…However, the yellow-white layer is so loose and thin that it can be scaled off easily. The XRD pattern from the sample without the yellowwhite layer indicates that the TE products only consist of TiC phase without any residual reactant and impurities such as the oxides and nitrides of Ti, as shown in Figure 1(b) (2). Therefore, it can be concluded that the forming TiC reaction from the Ti and C powders can be successfully initiated under air at a relatively low temperature.…”

“…However, it could be more amenable for preparing dense composites under external pressure application than the PWP mode. [2] The reason is that the TE reaction completes instantaneously without the propagation of combustion wave, which helps to implement fast densification under external pressure. However, the continuous propagation of the combustion wave increases the reaction completion time, which delays the quick implementation of external pressure and certainly weakens the densification.…”
