Bulk Al85Ni5Y8CO2 alloys with high strength above 1000 MPa were synthesized in each structural state of a mostly single amorphous, amorphous + fee-Al, amorphous + Al + Al3Y + Al3Ni and Al + Al3Y + Al3Ni phases by the hot-pressing consolidation method of atomized amorphous powders. The grain sizes of the crystalline phases are 30 to 50 nm in coexistence with an amorphous phase and 100 to 150 nm in the absence of amorphous phase. The fracture strength is 1050 MPa for the amorphous alloy prepared at the press temperature (T-p) of 473 K, 1130 MPa for the bulk amorphous + Al alloy at T-p Of 523 K, 1400 MPa for the bulk amorphous Al + Al3Y + Al3Ni alloy at T-p of 623 K, and 1430 MPa for the Al + Al3Y + Al3Ni alloy at T-p of 673 K. On the other hand, no distinct plastic elongation is seen for the bulk alloys containing amorphous phase and the disappearance of the amorphous phase causes plastic elongation of 1 to 2 % in the press temperature range up to 723 K. The fracture surface of the bulk amorphous + Al alloy consists of a well-developed vein pattern including a number of spherical particles which appear to correspond to fee-Al phase. The first syntheses of bulk amorphous or nanocrystalline alloys with high strength exceeding 1000 MPa by the powder metallurgy technique are encouraging for the future development of a new type of high strength material.
