TMM dedicates this issue as a tribute to Prof Telmo Roberto Strohaecker, who made a significant contribution to Metallurgy and Materials Science in Brazil during his very productive career. We have invited Prof Afonso Reguly, his former student and one of our Executive Editors and Prof Luiz Carlos Pereira, his colleague and collaborator in many endeavors since their PhD studies at COPPE-UFRJ to write this issue´s editorial.
