Cycle sequence sensitivity of near threshold fatigue under programmed loading – A fractographic study

[Display omitted] •Crack growth rates as low as 10−8 mm/cycle can be marked by suitable design of experiment.•Fractographic evidence confirms cycle-sequence sensitivity of near-threshold crack growth.•Reversal of peak-valley sequence of preceding larger cycle dramatically affects fatigue threshold.•...
