“…In this work, however, the increase of the TiO2/Al/C contents also affects the shape of Al2O3 altering it from a cluster to a more distributed shape in the form of a line along the NiAl matrix, which can be attributed to the self-diffusion of Al2O3 [11]. In particular, the existence of liquid NiAl allows the Al2O3 to rise to the surface due to its lower density [35].…”

Intermetallic-ceramic composites formed by the self-propagation high-temperature synthesis (SHS) process have attracted much interest in research development since they offer low-cost production and mechanical properties that have characteristically high performance. The objective of this work was to study the effect of reactant compositions on the combustion behaviour, microstructure and mechanical properties of the synthesized product of NiAl-TiC-Al2O3 composite. The reaction mechanism of the synthesized products was discussed based on the observations of the combustion reaction and the microstructure characterization. The results provided information on the relationship between the reactant composition, microstructure and the properties of the products of NiAl-TiC-Al2O3 composites formed by the SHS process.

“…This therefore suggests that TiC can be produced using low-cost material (TiO2). The formation of TiC with a fine grain size can be attributed to the fast cooling during synthesis since there is insufficient time for the formed crystals to grow [35]. The SEM micrographs shown in Fig.…”

“…The ceramic particles such as Al 2 O 3 , ZnO, SiC, B 4 C, BN and TiC are the materials which are explored earlier owing to their exceptional mechanical, electrical properties and also because of their availability [16][17][18]. Further it has also been reported that BN and SiC ceramic particles possesses excellent mechanical and corrosion resistant properties compared to other ceramic particles [8,[19][20][21][22][23][24][25].…”

Present study explores the effect of Rice Husk Ash (RHA) reinforcements in mechanically alloyed Al-BN-SiC hybrid composites through experimental characterization. The physical, tribological and corrosion resistance properties of Al-BN-SiC-RHA hybrid composites are studied. In the outset the composite pellets are synthesized using powder metallurgy process. The homogenously amalgamated composite powders are then squeezed together to form multiple green composite pellets each measuring 8 mm in diameter using a hydraulic press at a pressure of 500 MPa. The Al-BN-SiC-RHA hybrid composites are characterized using FE-SEM, EDS, and XRD analysis for facilitating the studies on the microstructural as well as the elemental properties. Microhardness and compressive strength of the Al-5BN-5SiC-5RHA hybrid composites is found to improve by 6 and 13.6% respectively compared to those of Al-5BN-5SiC hybrid composites. The RHA reinforced hybrid composites have also experienced reduction in density and an enhancement in the wear resistance of the composite materials while compared to those for their non-RHA counterparts. The electrochemical corrosion analysis of the Al-5BN-5SiC-5RHA hybrid composites also confirms that the Al-5BN-5SiC-5RHA hybrid composites have better corrosion resistance.

“…To solve these problems different types of reinforcing particle have been used to toughen the NiAl alloy. These include metals (Fe, Mo, Nb, W, Ti, Zr, Hf) [4][5][6][7][8][9][10], carbides and borides (TiC, SiC, B 4 C, TiB 2 ) [11][12][13][14] and oxides (Al 2 O 3 , Y 2 O 3 , Y 3 Al 5 O 12 ) [15][16][17][18]. To further expand the application range of NiAl matrix composites under high temperature, it is necessary to study the oxidation behaviour of NiAl composite in high-temperature environments.…”

Endogenetic particles TiB 2 (5 and 10 vol.-%)-reinforced NiAl matrix composites were fabricated in-situ from Ti-B-Ni-Al system by arc melting. The oxidation behaviour and anti-oxidant mechanism of TiB 2 -NiAl composite were investigated at 1173 K in air atmosphere. The composite had a rapid rate of oxidation during the first 20 h. With the increase in oxidation time, α-Al 2 O 3 oxidation films and needle-shaped TiO 2 phases were formed on the surface of the composite. As the Al oxidised into Al 2 O 3 , the NiAl phase transformed into γ-Ni 3 Al phase. The oxides were beneficial for improving the oxidation resistance of the composite. The mass change of the composite was less than 2.5 mg cm −2 after being oxidised at 1173 K in air atmosphere for 100 h. The composite showed excellent high-temperature oxidation resistance.
