The,re-lationship between retained austenite with its stability and TRIP has been analysed,the chemical compositions obtaining clear TRIP has been explored-This study also provlue basis for industrial production.

The shapes and morphologies, such as the retained austenite, ferrite, bainite ferrite, granular bainite, are clearly demonstrated in the dye microscopy with a special chemical etchant.

Study of retained austenite in the microstructure of austenitic-bainitic malleable iron;

Study on the quantity and distribution regularities of retained austenite in Q&P Steel;

The effect factors of the staility of retained austenite in austenitic-bainitic ductile iron;

Simple talk about the influence of residual austenite on steel;

Two separate tempering treatments at 670 ℃ is the most effective way to eliminate residual austenite in the carburized layer of steel.

The results showed that the main factors, which affected dimension changing of GCr15, included residual austenite content, tempering temperature and tempering time.
