Comparison of microstructural and mechanical properties of Al–TiC, Al–B4C and Al–TiC–B4C composites prepared by casting techniques

An alternative method for manufacturing Al/B4C/SiC hybrid composite strips by cross accumulative roll bonding (CARB) process

“…Alizadeh et al [17,22] have not observed any intermetallic compounds in Al/B4C and Al/SiC composite that was produced via ARB either. During casting of Al/B4C and Al/SiC composite, the injection of B4C and SiC particles to pure aluminum resulted in formation of deleterious intermetallic compounds such as Al3BC and Al4C3 [23,24] which affected properties of composites. It is observed in Fig.…”

“…B4C has lower density and higher hardness compared to Al2O3 and SiCp. Al-B4C composites can be processed by low cost casting routes [23]. But it is difficult to fabricate Al-B4C composites by mixing particles into the liquid phase, because of the poor wetting between Al and B4C below 1100 °C.…”

Self-propagating high-temperature synthesis of finely dispersed titanium carbide phase of powder mixtures in aluminum melt

“…Воздействие флюсов частично исследовано в работах [6,7,9], где было показано, что при менение натриевого криолита Na 3 AlF 6 благо приятно сказывается как на прохождении СВСреакции (1) в расплаве алюминия, так и на смачивании частиц TiC расплавом.…”

Al-TiC Composites Fabricated by a Thermally Activated Reaction Process in an Al Melt Using Al-Ti-C-CuO Powder Mixtures. Part I: Microstructural Evolution and Reaction Mechanism

“…[13,14] K-Al-F salts generated by the reduction of K 2 TiF 6 , in particular, were suggested to clean the particle surface and to remove the oxide layer from the surface of the melt, which improves the wetting of the graphite particles, promoting the formation of TiC. [17][18][19] Besides shortening the SHS reaction time, lowering the temperature that initiates a combustion reaction is of importance in a low energy and cost saving in situ process. Our recent study reported a very practical process of SHS combined with a conventional casting to fabricate in situ Al/TiC composites.…”
