抄録

A 70/30 brass specimen was subjected to the push-pull fatigue test under the low stress amplitude of ±8.4 kg/mm2 in water, using on ultrasonic fatigue tester. Observations by optical microscope showed that pits became visible on the surface slip markings at a very early stage (0.2% of presumed fatigue life), and on the grain boundaries and in the vicinity of inclusions at a later stage. The older slip markings had higher density of pits than new ones and the persistent slip bands started to grow at regions with the densest pits. Extrusions were also confirmed on and near the slip markings by electron microscope. Both pits and extrusions can be interpreted by the behavior of lattice vacancies.
