Empa - Shape Memory Alloys - A shape-conscious alloy
Low temp iron based SMA's make SMA reinforced prestressed concrete beams practical, which can be prestressed without elaborate tensioning systems. The only issue is the 160 degree transition temperature means if such a beam ever got exposed to a vehicle fire, it might fail faster than conventional prestressed concrete using steel rebar...
