METHOD FOR EVALUATING PRACTICAL CONDITIONS FOR USING ORDERLY ALLOY IN RADIATION ENVIRONMENTS (VARIANTS) Russian patent published in 2007 - IPC G01N23/00 G01N33/20 

FIELD: nuclear engineering.

SUBSTANCE: method for estimating practical conditions for usage of orderly alloy in radiation environments includes stages: receipt of irradiated state diagram, which reflects connection of far order power to variable R of irradiated state, connected to speed of damage and irradiation temperature, on basis of estimation formula, related to influence of radiation on far order power of orderly alloy, positioned in radiation environments, during usage as parameters of first threshold value, at which far order power begins to decrease substantially during irradiation, of second threshold value, at which far order power practically reaches balance after decrease, and far order power in balanced state, computation of variable R of irradiated state under conditions of irradiation, at which alloy subject to estimation will be used, and finding of value S of far order power, determining of first threshold value, second threshold value and far order power in balanced state for one and the same value R.

EFFECT: simplification of method, increased reliability.
