Al-based amorphous alloys containing finely dispersed fcc-Al particles were found to exhibit tensile strengths and hardness higher than those of amorphous single phase alloys with same compositions, in addition to good bending ductility. The Al₈₈Y₂Ni₉Fe₁ amorphous alloy containing 7% volume fraction (V_f) of the fcc-Al particles with a size of about 3–4 nm has a high tensile fracture strength (σ_f) of 1320 MPa and a specific strength (σ_f/density=σ_s) of 40×10³ m. Similarly, the mixed Al₈₈Y₂Ni₉Mn₁ alloy with V_f of 24% has 1260 MPa for σ_f and 38×10³ m for σ_s. It is notable that the σ_f and σ_s values for the former alloy are higher than the highest values (1140 MPa and 38×10³ m) of Al-based amorphous alloys. The high strengths combined with good bending ductility are presumably due to a dispersion hardening of the fcc supersaturated solution which has the hardness higher than that of the amorphous phase with the same composition.
