Development of a Force Parameter Model for a New Severe Plastic Deformation Technique – Multi-ECAP-Conform

Severe plastic deformation is one of promising techniques for omproving metal properties. In this work a new SPD technique – Multi-ECAP-Conform – is studied. The technique ensures an accumulation of a true strain degree to е>2.5 during one processing cycle. Models for force characteristics calculation have been developed on the basis of theoretical procedures of metal forming. The derived equations determine force parameters of the Multi-ECAP-Conform process.
