PURPOSE: To produce a high strength aluminum alloy consolidation material used for structural material for machine parts, etc. CONSTITUTION: This consolidation material is composed essentially of supersaturated solid solution phases of <=100nm average crystalline grain size and has >=1mm thickness, and further, the super-saturated solid solution phases are constituted as grains of 1-10μm average grain size. Moreover, the consolidation material has a composition represented by general formulae, Albal Ma Xb and Albal Ma Xb Qc [where M means V, Cr, Mn, Fe, Co, and Ni, X means Li, Mg, Si, Ti, Cu, Zn, Y, Zr, Nb, Mo, Ag, Hf, Ta, W, Mm, and rare earth elements, Q means B, C, N, and O, and the symbols (a), (b), and (c) stand for 0.5-10%, 0.5-10%, and <=5%, respectively). The consolidation material can be produced by an electron beam vapor deposition process. By this method, the high strength aluminum alloy consolidation material having new structure can be obtained, and, by using an electron beam vapor deposition process, a high density and high strength bulk material can be obtained directly from a master alloy.
