Abstract
Low cycle fatigue (LCF) tests of directionally solidified superalloy DZ125 were conducted with different holding time at 850°C. The tensile holding time of experiment was 1s, 60 s, 120 s and 240 s. Analysis of cyclic stress-strain, strain response, fatigue life, micro-fracture was carried out. The results indicated that holding time had significant effect to low cycle fatigue behavior. With the increase of holding time, the fatigue life decreased, but when the holding time exceeded a value, the fatigue life had the trend of becoming stable. In addition, creep damage played more important role as holding time increased.
