The optimum hot-working temperature for RR 58 [12793-49-6] Al alloy was 750 or 800 K for the electroslag refined or air-melted alloy, respectively. Hot ductility of the refined alloy did not increase, but the hot workability range shifted to lower temperatures of 750 K, to open up a possibility of achieving superior mechanical properties by thermomechanical treatment. The electroslag alloy was extruded at 750 K, and validity of optimum temperature predicted by hot torsion experiments was confirmed. The high-temperature deformation mechanism changed from self-diffusion in the air-melted alloy to dynamic recovery involving cross slip of screw dislocations in the refined alloy. An exponential rate equation was applicable.
