| Abstract |
The superplasticity of cast copper alloys used for solid cages is studied by tests of tension
and compression in this paper. The results show that cast copper alloys exhibited superplasticity
without any pretreatment. Cast aluminum bronze is of superplasticity at the temperatures between
750~800°C with the initial strain rate 1×10-2s-1, the elongation being over 260%. Under the condition
of superplasticity compression with the strain rate (1.136~9.091)x10-4s-1 at temperatures between
600~650°C, the cast lead brass presents the superplasticity effect with the maximum flow stress under
2MPa. |
