摘要：
The fatigue crack growth rate in the fast-fast strain cycles was accelerated by the introduction of one slow-fast strain cycle. It was also found that there was a linear relationship between the size of the region where the above acceleration occurred and the value of creep J-integral range which was produced just when one slow-fast strain cycle was introduced. The distribution of hardness just below the fracture surface, where the above acceleration occurred, was similar to the one in the pure slow-fast strain cycle fatigue.
