Abstract
Description
CO+H2→C+H2O [1]
上記分解反応[1]の平衡定数K1は、下記により定義される:
K1=(aC・PH2O)/(PCO・PH2) [2]
式中、Pxは、各ガス「x」のプロセスガス中の分圧(体積%/100)を表し、aCは、プロセスガスのいわゆる炭素活性を表す。上記分解反応[1]の平衡定数K1は、下記により近似させることができる:
10log(K1)=−7.494+7130/T [3]
式中、Tは、オーステナイト化温度(ケルビン)を表す。このようにして決定されたプロセスガスの炭素活性aCは、横断部材32の表面における平衡炭素含量、すなわち、プロセスガスと平衡状態にある(表面)炭素含量に関連付けることができる。図4のグラフは、3つのオーステナイト化温度についての炭素活性aCと平衡炭素含量ECC(重量%)との間のこのような関係を提供する。上記言及されたように、従来のオーステナイト化では、横断部材32は、中性プロセスガス中に置かれ、その炭素活性aCは、図4のグラフに係る平衡炭素含量ECCが横断部材32の基礎材料の炭素含量に実質的に等しくなるように定義される。
− 矢印1は、横断部材32の表面における残留圧縮応力の前記向上に関連する欠陥サイズDSに無関係な疲労強度の改善を示す。それによれば、完全な臨界疲労荷重線は、Kitagawa図において、右側にシフトする;
− 矢印2は、主に横断部材32の材料硬度の前記向上に関連する比較的小さい欠陥についての更なる疲労強度の改善を示す。それによれば、臨界疲労荷重CFLの曲げ点は、Kitagawa図において、上方および右側にシフトする;
− 矢印3は、基礎材料の前記粒度微細化に関連する欠陥サイズの減少による間接的な疲労強度の改善により、その加工性が改善することを示す。
