RR58 [12793-49-6] Al alloy was electroslag-refined by using a $KCl-MgCl_2-MgF_2$ synthetic slag. Electroslag refining decreased the macro- and microporosity and refined the microstructure to give a finely dispersed 2nd phase. The high-temp. strength was increased with a slight decrease in hot ductility. The optimum hot-working temp. was 750 K. The apparent activation energy estd. from the temp. dependence of flow stress in tension and of steady-state creep is 155 kJ/mol for both the refined and unrefined alloy. The value suggests a mechanism based on self-diffusion. In hot torsion, the alloy had a low activation energy which suggests a mechanism of dynamic recovery involving cross slip of screw dislocations
