Amorphous Al 86 Gd 6 Ni 6 Co 2 ribbons produced by melt-spinning were consolidated using twist extrusion (TE). Transition of the amorphous alloy ribbon into the crystalline state at 5K/min occurs via three stages in the temperature range from 473 to 673K. Formation of fcc Al nanocrystals is the dominant process in the first and second stages, which leads to increasing microhardness of ribbons from 360 to 620kgf/mm 2 . From one to five TE passes were performed on chopped ribbon in several experimental runs at temperatures between 458 and 573K and applied pressures between 1150 and 1700MPa. Full consolidation of the ribbons was achieved at TE temperatures ≥523K. The maximum microhardness (550kgf/mm 2 ) was reached in bulk materials consolidated at 513K with a nanocomposite microstructure consisting of about 57vol.% of Al-crystals with a size of about 13nm embedded in the residual amorphous phase. Extrusion at 573K resulted in full crystallization of the amorphous phase via precipitation of equilibrium intermetallics and lowering of the microhardness to 380kgf/mm 2 .
