Abstract

Rapid solidification technology (RST) has been shown to offer outstanding prospects of processing new cost-effective engineering materials with superior properties. There has as yet been only limited effort in the use of RST to synthesize new and improved copper-base alloys. A detailed investigation has been carried out to develop new coppernickel alloys by RST. These alloys find extensive use as condenser tubes, seamless tubes, etc.

New alloy systems suitable for processing by RST have been identified. These systems are as follows:

a) Cu-Ni-B

b) Cu-Ni-Al-B

c) Cu-Ni-Cr-B

d) Cu-Ni-Al-Cr-B

The preferred composition ranges and maximum attainable hardness for each system are given. It is of interest to note that the maximum hardness values attained for this system are around 500 Kg/mm2 which is much higher than the hardness of the conventional copper-nickel alloys.
