40Cu-W cup shell was successfully prepared by thixo-forging pseudo-semi-solid composites presented based on the powder metallurgy technology combining with semi-solid metal forming process.The bending strength and relative density reach 1151MPa and 98.38%

respectively

with forging pressure of 500MPa at 1350℃.The compact and homogeneous microstructure can be observed in the 40Cu-W cup shell.W particle is surrounded by Cu phase tightly

which is responsible for the improvement of mechanical properties of the parts.
