Effect of combining deformations at 77 K through drawing and quasihydroextrusion on the mechanical properties and structural state of steel 06Kh16H15M3B

We showed the effectiveness of applying a sequential combination of deformation at 77 K by drawing and quasihydroextrusion to obtain significant plastic deformations that enable high density of γ → α-conversions as well as considerable increase in the durability of the austenitic class steel 06Kh16N15. We explained the structural phase criterion for optimization of deformation contributions combining methods with varying epure of stress for austenitic state and determined that the final step must be a deformation method developing in an isotropic compression
