PROBLEM TO BE SOLVED: To provide a highly efficient method for improving the fatigue properties of a component formed by liquid phase diffusion joining by which excellent fatigue strength is imparted thereto, and to provide a component by liquid phase diffusion welding. SOLUTION: In the method for improving the fatigue properties of a component formed by liquid phase diffusion joining, the surface of a joint in a component subjected to liquid phase diffusion joining is struck with an ultrasonic vibration terminal vibrating at a frequency of 10 to 60 kHz and an amplitude of 0.3 to 50μm, and a level difference in the joint is reduced, thus the concentration of stress in the joint is relaxed. The component by liquid phase diffusion joining is obtained in accordance with the method. COPYRIGHT: (C)2006,JPO&NCIPI |
