ABSTRACT
This paper arose from a work on advanced simulation on casting wind powered turbine parts made from high tenacity ductile iron. The technical target was extracted from the Haizelan Project, carried out with Basque Country Foundrymen's Association (Spanish Foundrymen's Federation), two foundries, TS Fundiciones (Zestoa-Guipúzcoa) and Fundiciones Urbina (Urbina-Álava) as process suppliers and Gamesa Eólica (Huarte-Navarra) as part and geometry supplier. The study shows it is now possible to obtain highly accurate predictions in pouring and solidification using microstructure calculations simultaneously, and from then on good predictions about final microstructures and subsequent mechanical properties of castings. All related tasks in simulation were performed using FEM (Finite Elemets Method). Referred to metallographic studies and tests, which were done at Inasmet-Tecnalia laboratories.
