Abstract  

Al/Al2O3 cup shells with excellent mechanical properties were prepared successfully by thixoforging in pseudo-semi-solid state proposed based on the powder metallurgy technology and semi-solid metal forming process. Bend strength and fracture toughness of 37% (mass fraction) Al/Al2O3 are about 570--690 MPa and 8.5--16.8 MPa ? m1/2 respectively. It showed that the technology parameters have great influences on the mechanical properties. All results show that the composite presented is propitious to be used in more fields as the ceramic composites and high-melt point materials.

Key words:  composites      thixoforging in pseudo-semi-solid state      technology parameter      influence
