Abstract

The X-ray micro-diffraction laboratory technique was applied to study the quantitative changes of austenite content in TRIP steels after deformation and to reveal the phase composition of precipitates in an inner part of a hearth of a blast furnace. The usefulness of this technique was shown by calculating the austenite content after tensile test in three different parts of a small tensile test sample and after a clinching test in two areas of a clinching joint. The calculations showed the decrease in austenite content in deformed parts in comparison to not deformed areas. The presence of various kinds of chlorides, including the iron oxide chloride hydroxide in a sample taken from a graphite refractory lining of blast furnace, was confirmed by micro-diffraction patterns.
