It has been demonstrated that an acicular microstructure produces a loss of ductility independently of its morphology. However, this morology has a strong influence on toughness. The coarse acicular microstructure obtained by air cooling from the β phase shows the highest toughness. However, the fine needles of α′ martensite produced by water quenching from the β phase have the lowest values. The different fracture mechanisms and the crack growth path tortuosity justify this change in behaviour.7spainfo:eu-repo/semantics/restrictedAccessjournal articleFísica de la materia condensadaQuímica física y teóricaMetales y aleacionesQuímica de los materialeshttp://www.scopus.com/inward/record.url?scp=0024112931&partnerID=8YFLogxK
