Al-Cu alloy castings are obtained using centrifugal casting. The regularity of mechanical property gradient distribution of Al-Cu alloy castings with the same centrifugal radius at different positions is investigated. The result shows that the tensile strength, yield strength, elongation and...

The modified Peirel–Nabarro model of dislocations is not valid for the superdislocation bounded by the antiphase domain boundaries in long-range ordered intermetallic. In this work, a new Peirel–Nabarro Stress model is developed to take into account the critical resolved shear stress of...

Nanocomposite nc-TiC/a-C:H films, with an unusual combination of superhardness and high elastic recovery, are prepared by using dual plasma technique. The effect of the filter coil current on the compositional and structural properties of the nc-TiC/a-C:H films has been investigated. It is found...
