Al/TiB2 metal matrix composite (MMCs) was fabricated on aluminium AA1200 with the aim of improving the wear resistance property of the substrate. The characterization of the MMCs was carried out by Optical Microscopy (OM), Scanning Electron Microscopy (SEM/EDS) and X-ray Diffraction (XRD). The microhardness and wear resistance tests were achieved. Results showed that the microhardness property of the AA1200 was increased by three times the original value and the wear resistance was also significantly improved.

In situ high-energy X-ray diffraction using a synchrotron source performed on a steel metal matrix composite reinforced by TiC allows the evolutions of internal stresses during cooling to be followed thanks to the development of a new original experimental device (a transportable radiation furnace with controlled rotation of the specimen). Using the device on a high-energy beamline during in situ thermal treatment, we were able to extract the evolution of the stress tensor components in all phases: austenite, TiC, and even during the martensitic phase transformation of the matrix.

Stir Casting

The aluminium based composites are increasingly being used in the transport, aerospace, marine, automobile and mineral processing industries. The widely used reinforcing materials for these composites are silicon carbide, aluminium oxide and graphite in the form of particles or whiskers. In this study Al6061-6 & 4wt% Al2O3 based metal matrix composite were produced by mechanical stir casting process. The obtained cast metal matrix composite is carefully machined to prepare the test specimens for hardness, tensile as well as fracture toughness studies as per ASTM standards. The hardness, tensile strength and fracture toughness properties of Al6061-Al2O3 composites are explored experimentally. Finally compare the material characterization with heat treatment process sample and compare the fracture toughness of sample with mathematical approach, experimental and finite element method.

Casting Technique

Copper based TiC reinforced in-situ metal matrix composite was synthesized by melting copper, hexaflurotitanate and graphite powder in appropriate proportion at a temperature of 1100 °C using stir casting technique. Both copper matrix and copper-TiC composite were subjected to microstructure studies, x-ray diffraction analysis, hardness and tensile test. Optical micrograph shows fine and uniform distribution of TiC particles throughout the matrix. X-ray diffraction analysis confirms the formation of Titanium carbide particles. Developed composite exhibit a significant improvement in hardness and ultimate tensile strength compared with unreinforced copper.
