Al86Ni7Y4.5Co1La1.5 (at.%) alloy powder was produced by argon gas atomization process. After high-energy ball milling, the powder was consolidated and extruded by using vacuum hot press sintering under different process conditions, sintering temperature, extrusion pressure, sintering time, etc.. The microstructure and morphology of the powder and consolidated bulk alloy were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The phase transformation of the powder was investigated by differential scanning calorimetry (DSC). Mechanical properties of the consolidated bulk alloy were examined. The results showed that as the milling time increase, the volume fraction of amorphous materials and the hardness and yield strength of the bulk alloy were obvious improved.

High energy ball milling was used to preparation SiC/Al composites flakes. The research found the milling parameter of high energy milling was the ball/powder ration is 20:1, the rotary speed is 800 r/min, the milling time is 100min.Also researched the molding process of SiC/Al composites, the change of grain size and the weight fraction of the SiC, The research also found the mechanical properties of SiC/Al composites affected by the molding process. It was found that to reduce particle size and increasing of weight fraction of SiC, tensile strength of the SiC/Al composites increased. When the weight fraction of SiC in the SiC/Al composites is about 16%, the mechanical properties of SiC/Al composites about the hardness and tensile strength also get the high-point, the hardness and tensile strength is about 95HB and 248MPa.
