Predictive stainless phase design

Purpose and goal

Aim and objective of the project was the best possible tool for thermodynamic calculations for the development of stainless steels, now available to the partners of the project. In addition to this, the project has successfully solved a number of questions for stainless steel calculations and has been an important platform for the exchange of experience between experts in stainless steels and experts in thermodynamic modeling. The deliverables from this project will be the tool of choice for the development of future stainless steels and optimize critical heat treatments.

Expected results and effects

Results and expected effects, i.e. the database from this project is now with the project participants and can be used in the ongoing work and in ongoing research projects. A workshop has been held to inform outside the project group about the project and to provide an opportunity for questions. The project has made unique tools available that will provide a very important competitive advantage internationally and results and effects will make a lasting contribution to Sweden´s stainless steel industry being able to maintain and strengthen its leading market position.

Planned approach and implementation

The project was carried out in two parts: Equilibrium matrix phases 1000-1200 °C and Secondary phases <1000 °c. phase 1 consisted of a gap analysis and discussion and decision about lab melts and planning of experiments. phase 2 consisted of the experimental work, metallography and inserting and designing the new database. this was followed by an evaluation of outcome and necessary adjustments. the modeling work has been supported by experimental alloys in aim of exploring critical stainless issues, experimental results from all parties and detailed metallography.>
