Study on Preparation and Mechanical Properties of W-Cu Alloy with Low W-W Contiguity

摘要：

　　Electroless copper plating method combined with spark plasma sintering (SPS) was used to fabricate W-Cu alloy with low W-W contiguity.Results show that W-Cu alloy with low W-W contiguity and high relative density can be obtained by this method.With sintering temperature increased from 860℃ to 1060℃, the relative density of W-Cu alloy shows a rapidly increasing tendency, but the W-W contiguity keeps at a low level.Compression testing results show that the ductility of prepared W-Cu alloy is sensitive to strain rate, and the failure strain of the W-Cu alloy shows obviously increasing tendency with the loading strain rate increased from 10-3 to 103.
