1Effec"ts of Initial Microstructure Characteristics on Thermoplastic Deformation Behavior of Ti-55511 near β Titanium Alloy AITranslate
Abstract AITranslate
Hot compression was carried out on a Gleeble—3500thermal simulation testing machine of Ti-55511 alloy with the initial microstructure characteristics of pureβ,globularα,thick lamellarαand thin lamellarα,respectively.Plastic flow behavior of the alloy was studied at 700~800 ℃ deformation temperature and 10-3~10-1 s-1 strain rate.Investigation was made of the effects of initial microstructure characteristics on alloy thermoplastic deformation behavior.The results indicate that the flow stress of all the alloys with different initial microstructure increases with strain rate increasing and formation temperature decreasing.The order of deformation difficulty is pureβalloy>thick lamellarαalloy>thin lamellarαalloy>globularαalloy.The instability zones are mainly distributed at low temperature and high strain rate zones in the processing map.With the increase of deformation strain,instability area of globularαalloy gradually decreases while the instability areas of all the other alloys increase at first and then decrease.The differences of alloy deformation behavior are related to the microstructure evolution during deformation such asβ→αphase transformation,plastic instability of lamellarαphase,fragmentation and globalization ofαphase,shearing deformation and local plastic flow.
