Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To relieve the working strain, accumulated in crystals resultant from plastic working, by means of treatment at ordinary temp. in a short time by applying ultrasonic vibrations to a metallic conductor for audio and video use for relieving the working strain resultant from plastic working. SOLUTION: After a metallic conductor, constituted of copper, silver, aluminum, or an alloy composed essentially of them, is subjected to plastic working at >=75% draft, ultrasonic vibrations of 10 to 500 kHz frequency is applied to the metallic conductor for >=1 min. By the application of ultrasonic vibrations to the material after heavy working, the material is gradually softened by the application of vibrations for about 30 sec or more, through a temporary increase in the hardness of the material takes place for about 30 sec immediately after the starting of application of vibrations. The length of time required for shifting to softening is within 1 min in any case through there is an appreciable change due to the kind of material, the draft for the material, and the intensity and frequency of the ultrasonic waves.  Therefore, the lower limit of the application time of ultrasonic vibrations is set at 1 min.
