説明

On the present paper, preliminary experiments on the effects of cold-working upon the strainaging of Co-Cr alloy wires were performed. Each wire has the same constitution but different diameter. The author, in fact, estimated the effects of the amount of cold-working upon their mechanical properties at various temperatures of annealing for one hour. Results obtained were as follows : 1. It was found that the peak of hardening appeared by annealing at about 500℃. 2. The larger was the amount of cold-working, the more increased the aging effect. 3. Consepuently, this treatment may be recommended for the prosthetic application of the fine wires.
