Hybrid SPD process of aluminium 6060 for microforming

Abstract. The increasing share and expansion of miniature devices requires the mastery parts production, including metal parts. In microforming, due to conditions mechanical similarity, aim is use materials with smallest grain. Ultra-fine-grained metals (UFG) fulfill this requirement. These can be obtained, inter alia, in SPD processes such as ECAP. work uses extension based on ECAP additional forming operations necessary obtain blanks for microforming form a 0.2 mm foil. Three variants technological process were performed. This foil was then subjected micro-drawing operation aimed at determining influence preparation sheet flow.
