SPOFIC - Shrinkage Porosity Formation in Compacted Graphite Iron

Purpose and goal

The aim of the project was to facilitate the production of pore free cast CGI Components. This should be reached by building knowledge about formation mechanisms and quantification of the influencing parametrars. Metoden för kombination av termisk analys och volymsförändringar kan anses rätt genomarbetad, men en del praktiskt arbete återstår innan en robust analysutrustning för industrimiljöer kan realiseras.

Results and expected effects

The project SPOFIC has efficiently contributed to a increased research capacity in Sweden as well as to a fruitful collaboration between the Automotive industry, institutes and the academy. The technical progress within the project contributes to intact or improved competitiveness of the Swedish heavy duty automotive industry. The research has been presented at international Conferences and published in international, peer-reviewed journals and thereby independently quality checked. The results will mainly facilitate better material quality.

Approach and implementation

The originally planned six sub activities was partly dependent. Difficulties in part B caused therfore cancelaltion of part C as well as only partly fulfilled goals in part D. Due to limited knowledge on the area, the plan had to be updated with another three activities, G-I. In all, the project has delivered a satisfying amount of research results of a satisfying quality. The continuation project has less rigid formulated sub activities.
