## Description

- description: The high-cycle fatigue strength of 22Cr-12Ni austenitic stainless steel
    was evaluated at 77 K for three types of materials with partially recrystallized
    (PR), finely recrystallized (FR), and solution-treated (ST) microstructures. Subsurface
    crack initiation was detected at the lower stress level and/or higher cycles in
    the materials, such that the fatigue crack initiation sites were shifted from
    the specimen surface to the interior of the specimen with increasing cycles. The
    ST showed a significant decrease in fatigue strength over 106 cycles due to subsurface
    crack initiation. Both PR and FR showed a significant improvement in their high-cycle
    fatigue strength in the high-cycle regime, although the increase in fatigue strength
    in the low-cycle regime was approximately equal to the increase in tensile strength.
