Dear all, I have found deformation-enhanced phase transformation phenomenon in a TiAl alloy during hot tension. Now I need a kinetics model for this deformation-enhanced phase transformation. Can anybody tell me some literatures? Thanks!
See the following: (1) Characteristics of microstructural evolution during deformation-enhanced ferrite transformation in Nb-microalloyed HSLA steel; (2) Effect of Nb on the transformation kinetics of low carbon (manganese) steel during deformation of undercooled austenite; (3) Enhancing the stability of β phase in TiZr via severe plastic deformation; and (4) Mechanical properties of fine-grained dual phase low-carbon steels based on dynamic transformation.
I found this thesis on google search. It was too easy. Perhaps you already have a copy of it.
Best wishes.
@Ning Dang. Yes, the alloy is high Nb containing TiAl intermetallic, Ti-43Al-8Nb-0.2W-0.2B. I have ajusted the microstructure to be (beta+gamma) instead of the normal (alpha2+gamma). During tension, I found notable transformation from beta to alpha2, but no transformation observed in the grip region of the sample.
for most metastable austenitic stainless steels，such as 304 and 316， martensite transformation happens during tensile testing or cold rolling. the amount of martensite tranformation increases with the increasing of deformation.
you can find a lot of papers about martensite transformation and its model about metastable austenitic stainless steels
@Qiongqi Wang, @Ning Dang. Yes, it is somewhat similar with TRIP, but the major difference is that the present transformation is diffusion-controlled, not shear-induced. Thank you for all your useful answers.
