Fatigue damage of stainless steel diffusion-bonded joints
چکیده انگلیسی

Vacuum diffusion bonding was carried out on 316L stainless steel. Metallographic inspections and micro-hardness testing were conducted near the interface of diffusion-bonded joints. Fatigue tests were performed to investigate the mechanical performance of diffusion-bonded joints under cyclic loading. Results indicate that, although the static strength of joints closes to that of base metal, fatigue life of the diffusion-bonded joint is markedly lower than that of the base metal. Increments of electrical resistance of specimens were monitored and recorded at different cycles. By taking the electrical resistance as a damage parameter, the evolution of fatigue damage of diffusion-bonded joints was interpreted and the relationship between fatigue life and increments of electrical resistance was established. Overall good agreement between the experimental results and predicted life was obtained which provides confidence in the use of the developed approach for life prediction.
