The materials in semi-solid state have thixotropy and good histology

mechanical property is near to the forging.Synthesize the semi-solid metal forming

the powder metallurgy

we propose a new forming method for the metal toughed composite—thixoforming in pseudo-semi-solid state.And we prepared 37vol.%Al/Al2O3 cup shell successfully.We found the three-dimensional network structure in the cup shell by microscopic test.The interfaces bounded closely and distributed homogeneously.By the mechanical test

we found that the bend strength was about 570

6

90 MPa and the fracture toughness was about 8.5

1

6.8 MPa·m1/2.It showed that it had high bend strength and fracture toughness.At the same time

we analyzed the influences of technology parameters on the mechanical properties.By the comparison with other technology

the properties of it were higher than others.It was because of its technology characters.
