PROBLEM TO BE SOLVED: To provide a high strength aluminum alloy solidified material obtained by making a material (solidified material) having comprehensively excellent properties into the one having more excellent hardness and strength, and to provide a production method therefor. SOLUTION: The high strength aluminum alloy solidified material has a composition expressed by Al<SB>bal</SB>Ti<SB>a</SB>Cr<SB>b</SB>(a and b are atomic %, and 0<a≤20 and 0<b≤10), and the composition is mainly made up of a supersaturated solid solution phase or/and a superesaturated solid solution. In the production method therefor, the material grains are deposited on a substrate on which a vapor deposition material is deposited by an electron beam vapor deposition method, and further, the deposited material is subjected to heat treatment or hot working at 500 to 750 K.
