Irreversible deformation in a cubic metal on temperature change
- 18 Downloads
Temperature swings applied to cubic metals and alloys result in temperature hardening and temperature aftereffects.
In particular, a series of temperature shocks applied under conditions where the upper temperature exceeds the threshold Tcr accelerates the creep (no temperature hardening then occurs), while in the opposite case, the creep is retarded (when both effects occur).
A model is proposed that gives unified equations for rapid plastic strain within yield theory, as well as for creep and the above effects.
