Researches of influence ultra-fine grained structure of an aluminum alloy 1421 on electrochemical processing

The development of methods of processing of metals by pressure alloying to carry out the severe plastic deformations, has allowed last years successfully to use and for reception ultra-fine grained (UFG) materials with nanocrystalline and submicrocrystalline by structure. However, the electrochemical properties of materials with UFG by structure practically are not investigated. In particular, at electrochemical processing of details, which basic process is the anode dissolution, occurs at temperatures no more 50-60°C, that allows to receive continuous details with preservation UFG of structure. The purpose of the given work is the study of electrochemical properties UFG of structure in comparison with initial structure of an aluminum alloy 1421.
