Hydrogen Evolution from Polycrystalline Iron at a Constant Rate of Heating in Vacuum

A method for determining the amount of hydrogen evolved from iron samples using a constant rate of heating in vacuum has been developed. The method consists essentially of recording the flow rate of hydrogen evolved from a sample in a high-vacuum quartz tube, as a function of temperature, while the sample is heated at a constant rate from room temperature to 1000°C. The function is called the hydrogen evolution curve. The hydrogen evolution curves for several iron samples were studied.
