摘要
An irradiated state diagram that expresses a relation of a degree of long range order S to a variable R of an irradiated state related to a damage rate and an irradiation temperature is prepared according to an ordered structure of an alloy on basis of an evaluation formula related to an effect of irradiation on an irradiated state of the alloy by using, as parameters, a first threshold value SSUBth1 /SUBat which the degree of long range order begins to decrease greatly under irradiation, a second threshold value SSUBth2 /SUBat which the degree of long range order substantially reaches equilibrium after this decrease, and a degree of long range order in an equilibrium state SSUBeq/SUB. An R-value is calculated and an S-value corresponding to the R-value is found. An SSUBth1/SUB-value, an SSUBth2/SUB-value and an SSUBeq/SUB-value at the R-value are found and compared.
