Abstract

The flow softening behavior of AISI410 martensitic stainless steel was investigated by double hit compression tests in the temperaturer ange of 950–1100 C and the strain rates of 0.01,0.1, and 0.5 1/s. The tests were conducted withdelaytimesvaryingbetween1and50safterachievingastrainof0.1, 0.16 and0.2inthefirststage.Thefractionalsofteninghasbeenpredictedbytheoffsetstressmethod and thekineticequationshavebeenproposedtopredictthestaticrecrystallizationbehaviorofhot deformedAISI410martensiticstainlesssteel.Experimentalresultsindicatethattheflowsofteningisa functionoftheinter-passtimefordifferentstrainratesanddeformationtemperatures.Usinganalytical approach,thestaticrecrystallizationactivationenergyandkineticsmodelwasobtainedandbuilt. A goodagreementbetweenexperimentalresultsandpredictedvaluesofthemodelwasachieved.
