“…Selective electron diffraction patterns and their calibration results at the SiC/Al interface were given in Figure 9 b,c, respectively. The calibration results showed that there were only diffraction spots of SiC and Al, which were similar to the results of micron SiC particles [ 50 ], nano SiC particles [ 51 ] and graphene [ 48 ] reinforced aluminum matrix composites prepared by pressure infiltration, and no interface products (such as Al 4 C 3 , SiO 2 or Al 2 O 3 ) were found [ 52 , 53 , 54 , 55 ], which showed that SiC nanowires were not damaged during the preparation process.…”

In the present study, the effects of SiC nanowires (SiCnws) with diameters of 100 nm, 250 nm and 450 nm on the microstructure and mechanical behavior of 20 vol.% SiCnws/6061Al composites prepared by pressure infiltration were studied. It was found that the interface between SiCnws and Al matrix was well bonded, and no interface product was found. The thicker SiCnws are beneficial to improve the density. In addition, the bamboo-like and bone-like morphologies of SiCnws produce a strong interlocking effect between SiCnws and Al, which helps to improve the strength and plasticity of the material. The tensile strength of the composite prepared by SiCnws with a diameter of 450 nm reached 544 MPa. With a decrease in the diameter of SiCnws, the strengthening effect of SiCnws increases. The yield strength of SiCnws/6061Al composites prepared by 100 nm is 13.4% and 28.5% higher than that of 250 nm and 450 nm, respectively. This shows that, in nano-reinforced composites, the small-size reinforcement has an excellent improvement effect on the properties of the composites. This result has a guiding effect on the subsequent composite structure design.

“…moreover, it is also observed that some particles exist in some dimples, yet most of the dimples do not contain TiB 2 particles and thus it is decided that the failure of in situ composite is mainly caused by particle detachment. There is no evidence of particle fracture [38][39][40]. The particles and their surrounding regions are subjected to tensile load during the tensile test; the strongly embedded TiB 2 particles in the matrix are pulled out, resulting in the formation of dimples.…”

“…Both the siC and TiB 2 particles can withstand the compressive load effectively. The deformation caused by the indentation pressure is accommodated by the plastic flow of the matrix between the particles, and the particles are driven into the matrix material [40,46]. as a result, the hardness of the composites increases as the weight fraction of siC particles increases.…”

A CompArAtive Study on ex-Situ & in-Situ Formed metAl mAtrix CompoSiteS an attempt has been made to synthesize the aluminium based ex-situ (al-siC) and in-situ (al-TiB 2 ) formed metal matrix composites with varying weight percentage of reinforcement contents such as 4wt.%, 6wt.% and 8wt.%. synthesized composites were subjected to a cold extrusion process followed by heat treatment according to the asTm B 918-01 standards. The mechanical properties of in-situ composites were evaluated as per the asTm guidelines and compared with ex-situ formed composites and base metal properties. superior properties were noticed in the in-situ formed composites and the mechanical properties such as yield strength, Ultimate tensile strength (UTs) and hardness for both ex-situ and in-situ composites were found to increase with increasing the reinforcement addition. Cold extruded al-8 wt.% siC composite properties such as hardness, yield strength and UTs are 87 r B , 152 mPa, 216 mPa respectively. Whereas, for al-8 wt.% TiB 2 composite, the corresponding properties are 94 r B , 192 mPa, 293 mPa. The morphology of the composites is analysed by optical and scanning Electron microscopic (sEm) whereas presence of reinforcement particles such siC and TiB 2 along with intermetallic phases mg 2 si and al 5 Fesi are confirmed by EdX, Xrd and Element mapping analyses.
