“…The toughening effect might be attributed to the interaction between the crack tip and the externally added ceramic particles, i.e. crack‐deflecting and/or crack‐bridging effects as have also been effective in other composite systems where the matrices are brittle materials 15,16 . Moreover, the fracture toughness enhancement in the Ti 3 AlC 2 /ZrO 2 composite might also be attributed partially to the transformation of tetragonal zirconia particles into the monoclinic form in case a stress field is developed around the ZrO 2 particles.…”

A layered ternary carbide phase, Ti3AlC2, was synthesized by hot pressing from the starting materials of Ti, aluminum, and activated carbon at 1400°C for 2 h. Its composites were also fabricated through addition of micro‐sized SiC and partially stabilized zirconia particulates to the pulverized Ti3AlC2 powders. The polycrystalline Ti3AlC2 ceramic obtained has a flexural strength of 172 MPa and a fracture toughness of 4.6 MPa·m1/2, respectively. This compound is relatively soft (Vikers hardness of 2.7 GPa) and exhibits good electrical conductivity with an electrical resistivity of 8.2 μΩ·m. Both the Ti3AlC2/SiC and Ti3AlC2/ZrO2 composites are superior to the monolithic Ti3AlC2 ceramic in strength, fracture toughness, and micro‐hardness.

This paper presents the results on in-situ synthesis of refractory metal-intermetallic composites (RMICs), Mo-16Cr-4Si and Mo-11Cr-9Si (wt.%) multiphase alloys and their characterization. The alloys were prepared from the oxides of molybdenum and chromium by their coreduction with Si as reductant. Exothermic nature of the synthesis reactions resulted in the formation of consolidated composite as a product in a single step. As-reduced alloys were remelted by arc melting and heat treatment was given. The evolution of phases and the microstructure were studied by XRD, SEM, and EDS analysis. The multiphase microstructure consist of the silicide phases (Mo,Cr) 3 Si + (Mo,Cr) 5 Si 3 for hypereutectic and (Mo,Cr) 3 Si phase distributed in bcc matrix comprising essentially a solid solution of (Mo,Cr) for hypo-peritectic composition. Comparative studies of the synthesized alloys were also carried out to the composition, phases, microstructure, hardness and their oxidation behavior.
