Book Description
The major aims of this investigation were to determine the constitution diagram of the copper-zirconium alloy system in the zirconium-rich region and to evaluate the hardness properties of the alloys prepared. The following conclusions summarize the accomplishment of these aims. 1. In the copper-zirconium alloy system, with zirconium content above 60 weight-percent, an intermetallic compound, identified as CuZr2 and having a melting point of 1065 deg C, was located at 73.6 percent zirconium. The crystal structure of this compound is body-centered tetragonal, with unit cell dimensions of c = 11.3 + or - 0.2 A and a = 3.3 + or - 0.2 A. 2. A eutectic between CuZr2 and zirconium was located at 80.3 percent zirconium with a eutectic temperature of 998 deg C. 3. A eutectoid was located at 95.0 + or - 0.5 percent zirconium and 916 + or - 15 deg C. 4. No pyrphoric alloys were encountered in the region studied. 5. The addition of even very small amounts of copper to zirconium was found to give an alloy harder than that of the zirconium itself, and the hardness rose, in general, with increased copper concentration. 6. The extent to which oxygen has altered the various transformation temperatures herein reported, or increased the hardness. Only the possibilities can be acknowledged at this time.
