Curriculum Vitae
Paolo Ferro is actually Associate Professor of Metallurgy and Materials Selection at the University of Padua (Italy). After the degree in Materials Engineering (Summa Cum Laude) he received the Ph.D. degree from University of Padua in Metallurgical Engineering. From 2006 to April 2015 he served as Assistant Professor at the Department of Engineering and Management of the same University. He was scientific director of the research program 'Numerical and Experimental Determination of Residual Stresses in Welded Joints and their Influence on Fatigue Strength' (Young Researchers Project, 2003-2004). He won the prize for young researchers ‘Aldo Daccò’ 2002. He is a member of CMBM (Centre for Mechanics of Biological Materials). He is coordinator of the European project on Critical Raw Materials named DERMAP (Design of components in a critical Raw MAterial Perspective). His research is mainly focused on the analytical and numerical modelling of welding and heat treatment processes. He is interested in the local criteria based on the Notch Stress Intensity Factor (NSIF) and the Strain Energy Density (SED) averaged over a control volume for the evaluation of fatigue strength of welded joints. He works also on the modelling of intermetallic phases evolution during heat treatments of Duplex and Superduplex Stainless Steels and mechanical and metallurgical characterisation of Cast Irons with particular attention to heavy section DI castings and solution strengthened ferritic ductile irons (SS-FDI). He has published more than 130 papers in international peer-reviewed journals, conference proceedings and contributed book chapters (in SCOPUS data base: 79 documents, 607 citations, h-index = 16). In addition to his editorial role with Advances in Materials Science and Engineering and SciFed Journal of Metallurgical Science, he frequently serves as reviewer for many other professional journals and national as well as international funding agencies. He is scientific coordinator of the Italian research program on mechanical characterization of heavy section ductile irons

Research areas
The scientific activity of Paolo Ferro has been structured on various issues related to metallurgical processes and their influence on the final properties of the products they derive from.
His research has covered both issues of industrial interest (foundry, heat treatment and welding), carried out in collaboration with Italian and foreign industries, and theoretical aspects linked to machine design and metallurgy (i.e.: design criteria for welded and bonded structures, influence of phase transformations on residual and asymptotic stress fields induced by welding process). His initial training in the study of machine design (under the supervision of Prof. Paolo Lazzarin) and the subsequent deepening in the field of simulation of metallurgical processes, allowed him to integrate coherently and with original results the topics coming from mechanical engineering (i.e.: structural analysis) with those related to metallurgy (i.e.: phase transformations). The results of his research about Residual Notch Stress Intensity Factors (R-NSIFs) induced by welding were cited in the advance research topics of Diter Radaj’s book: Ermüdungsfestigkeit, Grundlagen für Ingenieure. 3. Auflage. Springer, 2007 (ISBN 9783540714590) (p. 254).
His research activity was carried out through a focalized approach on:
• the study of stress distribution induced by thermal loads and influenced by phase transformations;
• development of analytical, semi-analytical and numerical models of metallurgical processes with particular attention to heat treatments and traditional as well as innovative welding processes;
• experimental investigations of different metallic products microstructure and properties (foundry products, additive manufactured products, welded joints, innovative materials, heat treated alloys). Particular attention has been addressed to the microstructure-properties correlation.
Part of this research activity was also carried out within national and international research projects and collaborations (agreements) with national and international industries.
His recent research activities regard:
1. metallurgical and mechanical characterization of additive manufactured components and numerical simulation of additive manufacturing process;
2. R-NSIFs determination by means of Peak Stress Method (PSM). Numerical simulation of single and multipass welding process applied to large structures;
3. metallurgical and mechanical characterization of new generation ductile iron castings (Solution Strengthened Ferritic Ductile Irons, SS-FDI);
4. modelling of precipitation and dissolution kinetics of secondary phases in duplex and superduplex stainless steels.
