The forming limit stress curve (FLSC) is often recommended as failure criterion for the virtual tryout of forming processes which include non-proportional loading. However, parameters influencing position and shape of the forming limit stress curve a

The age-hardening response at 300 °C of Al–0.06Sc–0.02RE (at.%, with RE = Tb, Ho, Tm or Lu) is found to be similar to that of binary Al–0.08Sc (at.%), except that a shorter incubation period for hardening is observed, which is associated with
