The structure and the phase state of Al—Fe alloys for 5 up to 50 at % iron produced by plastic deformation under a pressure of 5GPa as splats are investigated. Small parts of metastable intemnetal-lic phases are formed in the inner of the grains. Like amorphous alloys the intermetallic structure shows a diffuse diffraction pattern by transmission electron microscopy (ТЕМ). The investigation of the thermal behaviour of the alloys is measured by the electrical resistance. An intensive formation of the metastable intermetallic phases begins above 400 °C with different structures demonstrated by transmission electron microscopy.
