Tensile ductility of directional solidified Fe-Ga alloys was significantly improved with Al addition.
The fracture elongation of binary Fe82Ga18 alloy was only 1.3% at room temperature.
The fracture elongation of Fe82Ga9Al9 alloy was 16.5% at room temperature.
A great number of deformation twins formed in the Fe-Ga-Al alloys during tensile tests at room temperature.
