The Difference

A natural, in-situ, metal-matrix composite Al-Nb with an intermetallic phase Al3Nb with a fraction of 25% at. was obtained by deformation shear under pressure and subsequent annealing. The microstructure of the composite was studied. The emission efficiency in the glow discharge of Al-Nb composite, as well as aluminum and niobium as cold cathodes, was determined. The analysis of the difference between the glow discharge current at fixed voltages for cathodes from the studied materials is carried out.

X Ray

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.

Casting Technique

The AA7075-4%TiC metal matrix composite produced through in-situ casting technique was hot extruded and subjected to annealing at 415°C for 150 minutes. Another set of hot extruded AA7075-4%TiC metal matrix composite was heat treated to T6 condition. Dry sliding wear test was conducted with different sliding speeds and loads for both annealed and T6 conditioned composites to compare their wear behaviour. It was observed that irrespective of the heat treatment conditions, the depth of wear, decreases with increasing sliding velocity for all the loads tested and increases with increasing load for all the sliding velocities.
