Light weight castings for Foundry
TITLES: Light weight castings for Foundry
The webinar, organized under the framework of the EU project NetCastPL4.0, spotlight Austempered Ductile Irons (ADIs) and highlight over a decade of scientific collaboration between CNR-ICMATE and Zanardi Fonderie S.p.A., a European leader in ADI production. Aligning with NetCastPL4.0‘s mission to foster a Networking Pole for knowledge exchange between research institutions and foundries, the seminars by Dr. Giuliano Angella (CNR-ICMATE, Italy) and Mr. Franco Zanardi (Zanardi Fonderie S.p.A., Italy) showcase how research-industry synergy drives innovation and sustainability in the foundry sector.

Austempering time optimization through tensile behaviour analysis: a refining procedure of Dorozil method
The Austempered Ductile Irons (ADIs) production consists of a two-step heat treatment of a conventional ductile iron: first, austenitization at high temperature to have homogeneous austenite rich in C; then, quenching in salt bath to trigger the isothermal austempering solid-state transformation. After a proper austempering time, the resulting microstructure is the dual phase acicular ausferrite, that is, metastable austenite rich in C (γHC) and bainitic ferrite (α). However, if the casting is held at the austempering temperature for longer times, the reaction γHC→ α + ε occurs, where ε is a FeC carbide that dramatically reduces the ausferrite ductility. The proper austempering time window can be found through an innovative procedure based on tensile strain hardening analysis that results to be more reliable than the traditional Dorazil method based on the tensile ductility analysis against the austempering time. Significant examples of the goodness of this procedure are here reported.

The importance of scientific collaboration between foundry and Accademia for materials engineering: the case of Austempered Ductile Irons
Austempered Ductile Irons (ADIs) are still considered as “new” materials and technologies after 50 years from the first industrial successful solutions, in Europe ADIs are not widespread as they should deserve, because of little awareness of austempering parameter production effects on the ADIs microstructure and of certain relationships between ADIs microstructure stability and mechanical properties. Professionals prefer to avoid the exploration of new development risks, even if they know that they could support great competitive advantages in long term perspectives, because the time necessary is out of their life scale. The case of Zanardi Fonderie is of great high-quality cooperation with a number of universities with activity of measurement and teaching, taking care directly about the deep evolution of new industrial technologies, assisting end users and professionals in developing new solutions also outside the proprietary supply chain perimeter. Examples of significant results from these collaborations are here reported.
