THE USE OF MODERN PHYSICAL METALLURGY IN THE DEVELOPMENT AND CHARACTERIZATION OF SPECIAL STAINLESS-STEELS

A selection of examples have been made to illustrate the use of microa nalytical instruments and thermodynamics in the development of steels. It has been shown that the combined use of electron microscopy, secon dary ion mass spectroscopy, atom probe field ion microscopy and the th ermodynamic computer program Thermo-Calc is a particularly powerful to ol in aquiring a deeper understanding of the the relation between micr ostructure and properties. It has also been demonstrated that Thermo-C alc can be used routinely in alloy development for predicting phase eq uilibria.
