Abstract

In order to clarify the deformation mechanism in the transient creep region, the instantaneous plastic strain and strain rate have been measured from an early stage to the steady state. The test has been carried out at temperatures from 623 K to 823 K and stresses from 0. 81 to 6. 7 MPa. Instantaneous plastic strain depends on stress. From the temperature dependence, it is concluded that the main part of instantaneous strain is produced by athermal motion of dislocations.
