DURING an investigation of the structure of a hardened 1½ per cent chromium steel, the presence of a small amount of retained austenite was observed in the microstructure. Examination of this material ...

TRIP steels have a microstructure consisting of at least five volume percent of retained austenite, which is embedded in a primary ferrite matrix. The microstructure also contains hard phases like ...

For many years, carburising has been amongst the most widely used processes for developing a hard, wear resistant layer on steel components. Fluidised bed furnaces have proven themselves to be very ...
