Conclusions
-
1.
Stabilization of small deformations of D16 and V95 alloys is caused primarily by stress relaxation in final decomposition of the solid solution initiated by deformation.
-
2.
Aging under stress after small deformations provides the obtaining of accurate parts with small curvature in sheet stamping of dispersion hardening alloys.
