Abstract
In a stress corrosion cracking evaluation method for a steam turbine, a sample having a high sensitivity is housed in a sample box of the steam turbine, and a sample breakage time is acquired. Then, based on the sample breakage time, a breakage time of the steam turbine is estimated.
Claims13
A stress corrosion cracking evaluation method for a steam turbine, comprising:
- a sample breakage time acquisition step of acquiring a sample breakage time of a sample which is housed in a sample box of the steam turbine and is configured to have a higher sensitivity to stress corrosion cracking than an evaluation object material of the steam turbine;
- and
- a breakage time estimation step of estimating a breakage time of the steam turbine based on the sample breakage time.
