Abstract

The sheet metal pressing structures produced by hydromechanical forming of nickel superalloys were analyzed to determine effect of plastic deformation on the structure and mechanical properties of finished products. The Inconel 625 nickel-alloy sheet metal was extruded with liquid in the form of cones. The drawpieces were mechanically divided by cutting into main cross sections. An analysis of local deformation distributions, structure deformation level and distribution of alloy components on these sections were evaluated. It has been shown that the plastic deformation carried out by liquid forming (hydroforming) or by a liquid through an elastomeric membrane preserves the original structure and properties of the sheet metal input level, only with the effect of work hardening of tested alloys.
