A new technical method has been developed on the analytical system which can provide us with the information about the phase of nonmetallic elements, such as carbon, sulfur and nitrogen, in steel.
When a finely-milled steel sample is isochronally heated in a hydrogen stream, nonmetallic elements react with hydrogen forming hydride-gases. The hydrides are at real-time analysed by a mass-spectrometer in relation to the heating temperature. From the temperature and the amount of gas detected, the phase of nonmetallic elements in steel is analysed.
