抄録

Fatigue tests were conducted on specimens of ultrafine grained copper produced by equal channel angular pressing. The growth behavior of a major crack, which led to the final fracture of the specimen, was monitored successively. Propagation behavior of the crack was influenced by damaged zone ahead of the crack tip, and consequently different morphologies of the fracture surfaces developed, depending on the stress amplitude and crack length. The change in fatigue fracture surface morphologies was occurred from a change in crack growth mechanism and was qualitatively explained by considering the interrelation between grain size and the reversible plastic zone size at the crack tip.
