Title:
METHOD FOR ESTIMATING USE TEMPERATURE OF HEAT RESISTANT MEMBER
Document Type and Number:
WIPO Patent Application WO/2016/151954
Kind Code:
A1
Abstract:
Provided is a method for estimating the use temperature of a heat resistant member which makes it possible to quickly estimate the use temperature of a heat-resistant member by using a comparatively simple operation. The method has: a replica creation step (S1) for creating a replica obtained by transferring the surface structure of the heat-resistant member; a carbide image creation step (S2) for creating a carbide image on the basis of the replica; a carbide amount derivation step (S4) for deriving a carbide amount on the basis of the carbide image; a Larson-Miller parameter derivation step (S5) for deriving an LMP corresponding to the carbide amount, by using the carbide amount and a master curve, which is a diagram created in advance of the correlation between the carbide amount and the Larson-Miller parameter; and an estimated equivalent average temperature derivation step (S6) for deriving an estimated equivalent average temperature by using a relational expression between the LMP, absolute temperature T (estimated equivalent average temperature), and use time t.
