At present aluminum is reinforced mainly with the help of nanopowders, but this is an extremely expensive and time-consuming process. Researchers in Russia have demonstrated that if a melting technique is used, after Al-Ni-La crystallization, the diameter of doping particle does not exceed 30-70 nanometers. Due to natural crystallization, particles are distributed uniformly, forming a reinforcing structure. Hence, the composite becomes stronger and more flexible than its powder analogues. The important feature of the new development is the high reinforcing ability of the chemical compounds with ultrafine structure: the diameter of the reinforcing elements does not exceed several tens of nanometers…read more.
