摘要：
Methods for monitoring a heat treating atmosphere supply a preselected gas atmosphere at a preselected temperature to a heat treating furnace. The preselected temperature is not greater than a temperature at which wustite (FeO) forms. The methods sense the preselected gas atmosphere and the preselected temperature and compute a computed ratio of gaseous hydrogen H2 (g) to water vapor H2O (g) for the preselected atmosphere as a function of the sensed values.
