Abstract

Abstract: To investigate the effect of fatigue-creep interaction on the life of Powder Metallurgy (P/M) superalloy turbine disks under asymmetric loading, low cycle fatigue-creep tests of the P/M FGH96 superalloy are conducted at 550℃ at different stress levels and holding time, obtaining its cyclic strain response and the variation of fatigue-creep life. A fatigue-creep life prediction method based on cyclic strain characteristics is proposed. The new model takes the cyclic strain range as the damage control parameter which correlates with the load holding time and the dynamic cycles. The influences of the load history and holding time on the fatigue-creep damage are comprehensively considered, and the fatigue-creep life prediction and dynamic tracking of consuming life for FGH96 at different stress levels and within different holding time can be realized. Compared with other life prediction models, the new model owns high prediction accuracy with small dispersion of prediction. The life prediction results are mostly within ±2.5 times of the scatter band, and the standard deviation is less than 0.4.

Key words: asymmetric loading, powder metallurgy superalloy, turbine disks, fatigue-creep, cyclic softening, load holding time
