| 2 | Wrought processing of γ-TiAl alloys显示文摘The hot working behaviour of intermetallic titanium aluminide alloys was described. The microstructural evolution during hot working was systematically studied on a series of binary and technical alloys with aluminium contents ranging between 45% and 54%(mole fraction). Process regimes in terms of temperature and strain rate were identified which allow large strain hot working to be carried out, either by forging or extrusion, with the production of sound forgings. The major areas addressed in the paper are ingot structure and homogenization, factors determining hot working and recrystallization, ingot conversion, and secondary processing. | M.Oehring, F.Appel, U.Lorenz (Institute for Materials Research, GKSS Research Centre Geesthacht, D-21502 Geesthacht, Germany) | 2002 | 中国有色金属学会会刊:英文版2002，12，4： | 1 |
