| Abstract |
| The effects of Sn contents on the mechanical properties and the role of Sn in the Cu-9Ni-xSn alloys have been investigated and the following results have been obtained. The mechanical properties such as tensile strength, elongation and electrical resisitivity of Cu-9Ni-xSn alloys are strongly dependent on aging temperature, aging time and Sn contents. With increasing Sn contents, the tensile strength is increased and the temperature where the spinodal decomposition occurs and the incubation time to start spinodal decomposition are lowered and reduced, respectively. By aging treatment at temperatures below 350℃, the 5%Sn alloys. In the case of the 5%
