Abstract
Aluminum-lithium alloys are a new class of well-known aluminum systems and are characterized by excellent combination of mechanical properties, low density, increased elasticity modulus, and sufficiently high strength. This allows the creation of aerospace technology with a smaller mass, which gives the opportunity to save fuel, increase load capacity. Selection of lanthanum as an alloying element because it has a modifying effect on the structure of the alloy is beneficial to the corrosion resistance of aluminum. On the phase diagram Al-La by attaching aluminum eutectic reaction F-Al + LaAl4 at a concentration of 12% and 624°S. The solubility of lanthanum in solid aluminum is 0.05% at the eutectic temperature. The hardness, strength and elongation of aluminum virtually unchanged from administration of lanthanum. The last decade is characterized by the rapid expansion of the range of new, mainly plastics, metals and alloys, however, have been and remain the main structural materials in the manufacture of machinery, equipment, appliances, building construction, transportation and communications. In this regard, the improvement of methods and means of corrosion control is important not only for the possibility of reducing the economic loss from corrosion, but also to provide further technical progress.
