Abstract
【解決手段】本発明に係る鉄系酸化物分析方法は、試料表面にX線を照射し、試料表面からの鉄系酸化物のX線回折強度を鉄系酸化物の形態毎に測定する測定ステップと、測定ステップにおいて測定された鉄系酸化物の形態毎のX線回折強度を用いて、鉄系酸化物の酸素付着量及び形態別の存在量を定量する定量ステップと、を含む。本発明に係る鉄系酸化物分析方法によれば、多くの労力を要することなく、迅速、且つ、非破壊で鉄系酸化物の存在量を鉄系酸化物の形態別に定量することができる。

Description
雰囲気制御可能な加熱炉内で、大きさ7cm×18cmの冷延鋼板をN2ガスにO2ガスを0.1〜2%混合した雰囲気中で最高到達温度400〜850℃まで加熱し、鋼板表面に鉄系酸化物薄膜を作製した。このとき、所定温度到達後に冷延鋼板をN2ガスで急冷し、さらなる表面酸化を抑制した。このようにして作製した鉄系酸化物薄膜付き冷延鋼板の一部を大きさ0.5cm×1.0cmに2個ずつ切り出して溶解分析を行い、その平均から鉄系酸化物薄膜中に含まれる単位面積あたりの酸素量、すなわち鉄系酸化物の酸素付着量を算出した。
