As bobw indicates, one needs to consider the relative thermal expansion rates of the two dissimilar materials here. Aluminum expands about twice as much as steel at the same temperature. Heating the aluminum and cooling the steel screw will maximize any potential gap between the two pieces allowing for the possible entry of a penetrant.

Note the words “potential”  and “possible” …. a bit of old fashioned luck may come into play as well
