摘要：
Fatigue life and notch sensitivity of the ultrafine-grained pure Ti produced by equal channel angular pressing (ECA-P) was investigated. The ECAPed Ti showed a significant improvement in its high cycle fatigue limit (by a factor of 1.67) but its notch sensitivity was increased. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd.
