M.K. Knyazyev, D.M. Tkachenko, Ya.S. Zhovnovatyuk

Analytical overview of the benefits of electrohydroimpact forming comparing with traditional methods and description of cold forming influence on microstructure of an aluminium alloy were considered. Brief description of experimental study of impact forming influence on the D16T alloy microstructure was described. Comprehensive analysis of the D16T alloy microstructure and identification of structural changes after impact deformation were carried out. Quantitative characteristics of a grain and sheet metal deformation were determined. Directions for further researches were defined.

Key words: impact, forming, sheet metal, deformation, grain, microstructure.
