EVALUATION METHOD AND DEVICE FOR EVALUATING MATERIAL DETERIORATION BEHAVIOR BY TRACER HYDROGEN

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method and device for measuring/evaluating precisely and easily a deteriorated/damaged state inside a material, by releasing hydrogen in a practical material by temperature elevation release analysis to analyze the released hydrogen obtained therein.;SOLUTION: The hydrogen captured or solid-dissolved in the material is released to an outside of the material by temperature elevation, and a material deterioration behavior is evaluated based on information obtained by the temperature elevation released hydrogen. The evaluation method/device include with a heating means for eliminating/releasing the hydrogen captured or solid-dissolved in the material, a collection means for collecting the eliminated/released hydrogen, a hydrogen information acquisition means for acquiring information as to the temperature elevation released hydrogen, and an information analytical means. The deteriorated/damaged behavior inside the material is investigated based on an elimination characteristic of the hydrogen captured in a deteriorated texture.;COPYRIGHT: (C)2007,JPO&INPIT
