摘要：

Bulk copper alloys with nano TiB2 particles were prepared by a new technology that combining in situ reaction with rapid solidification. Appropriate reactor shape and procedure parameters are as follows: S-0/(S-1 + S-2) = 0.8-1.2, L-0/D-0 = 10-15, theta = 60-90 degrees, melt temperature 1350-1450 degrees C, air pressure 0.2-0.3 MPa. A special water-cooled copper mold can satisfy the need of rapid solidifying Cu-TiB2 alloy melt. The average size of TiB2 particle in the copper matrix synthesized by using optimal parameters is about 20 nm. (c) 2007 Elsevier B.V. All rights reserved.
