以XRD、SEM/WDS和TEM分析结果为依据,对Fe-Mo(Mo=20%~57%)二元合金在硫蒸气中(PS2=1~50kPa)高温硫化产物层的相组成及膜层中的有关固态反应进行了探讨,绘出了可能的稳定相图,分析了主要硫化产物的缺陷结构特点及其对硫化传质的影响.认为Fe、Mo混合硫化物中的缺陷密度较高,对传质的阻力较小;而MoS2层缺陷密度小,对阻止硫化反应物传质起主要作用.

A discussion has been made on the solid state reaction and scale structure for Fe Mo alloy, according to the results through XRD, SEM/WDS and TEM observations. A hypothetical stable phase diagram is presented. The correlation between the defect properti
