CREEP SPEED DISTRIBUTION EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a creep speed distribution evaluation method capable of accurately estimating the creep speed distribution at different positions of a component member.SOLUTION: The creep speed distribution evaluation method S1 of the present invention includes: a test piece preparation process S11 of preparing a plurality of test pieces from different positions of a component member, respectively; a tensile test process S12 of acquiring the tensile strength of each of the plurality of test pieces by applying a tensile test to the plurality of test pieces; and a creep speed distribution estimation process S14 of estimating the creep speed distribution in the component member on the basis of the tensile strength acquired in the tensile test process S12.
