primary creep


فارسی

1 متالوژی:: خزش اولیه

Primary creep in austenitic alloys has not been extensively investigated over large ranges of temperature. Creep mechanism in MAR-M 200 single crystals at 1400F have been reported (Leverant and Kear, 1970), with primary creep strain and rate indicating sensitivity to orientation. A constant volume fraction causes larger particles to be more ben- eficial in restricting primary creep, as the line tension precludes penetration of the particles. Development of a substructure during primary creep and after substantial strain hardening helps in raising the steady-state creep in MAR-M 200 at 1400F. properties because of the formation of   during the primary creep.
