The alpha-beta annealed samples exhibit a higher toughness compared with the original mill annealed condition, reaching, after 4 hours at 900°C a similar level to beta heat treated and air cooled specimens. The very slight decrease in ductility of these samples makes this treatment very promising.5enginfo:eu-repo/semantics/restrictedAccessconference outputGeneral Engineeringhttp://www.scopus.com/inward/record.url?scp=0024863942&partnerID=8YFLogxK
