Abstract A study on the diffusion reaction of melted Al and (Fe0.99, Mo0.01)78Si9B13 amopohous alloy was carried out under a pressure of 3 GPa at temperature ranging from 570 to 850℃. A bulk Al-Fe(Mo,Si,B) nanostructured alloy composed of a single phase was prepared by heating alternate layers of (Fe0.99, M0.01)78S9B13 amorphous ribbons and pure Al sheets for 20 min under a pressure of 3 GPa at temperatures of 800 to 830℃. Its mean grain size is 22 nm and its lattice is orthorhombic. Its thermostability is fairly good and its hardness is 6.9 GPa.
