摘      要：The microstructures and mechanical properties of Als9 GdTNi3Fe alloy extruded from its amorphous powder were investigated at different temperatures. Devitrification process of amorphous phase was also analyzed. As a result, the microstructure of the extruded alloy consists of fee α-Al, binary intermetallic Al3Gd and ternary intermetallic r l phase. The grain size of α-Al is fine. The intermetallic Al3Gd exists as equiaxed particle and τ1 phase appears rod like.
