The Influence of Prior Creep on the Fatigue Strength of AK4-1-T1 Alloy (Vliyanie Predvaritelnoi Polzuchesti na Vynoslivost Splava AK4-1-T1),
Abstract
Results are given from an experimental study of the effect of prior creep at moderately elevated temperatures on the fatigue characteristics of notched specimens of AK4-1-T1 alloy. It has been shown that the effect of creep on fatigue strength is governed by a large number of factors (structural changes and relaxation of manufacturing residual stresses, dependent on the long-term action of temperature; residual stresses formed in regions of stress concentration as a result of non-uniform total creep; cold working; formation of microcracks or voids), which may either decrease or increase fatigue life.
