Creep Mechanisms and Interface-Enhanced Deformation Twinning in a Two-Phase _ Lamellar TiAl Alloy
Deformation mechanisms and the role of interfaces in deformation twinning of a two-phase [TiAI (y)GAl (ad] 1 amellar allo\t creep deformed at elevated temperatures have been investigated. Since the multiplication of lattice dislocations \vithin both y and a2 lamellae is verl\’ limited at a lo\v stress level due to a refined lamellar microstructure, the glide of interfacial dislocations on both ...
متن کاملAn Atomistic Study of Interfacial Diffusion in Lamellar TiAl Alloys
In this paper we investigate self-diffusion of Ti and Al along interfaces present in the lamellar L10 TiAl by atomistic computer modeling. The interactions between the atoms are described by centralforce many-body potentials. The approach adopted is similar to that used in earlier atomistic modeling of bulk diffusion in TiAl [1, 2]. Both the formation and migration of vacancies is examined. The...
متن کاملAccessing Colony Boundary Strengthening of Fully Lamellar TiAl Alloys via Micromechanical Modeling
In this article, we present a strategy to decouple the relative influences of colony, domain and lamella boundary strengthening in fully lamellar titanium aluminide alloys, using a physics-based crystal plasticity modeling strategy. While lamella and domain boundary strengthening can be isolated in experiments using polysynthetically twinned crystals or mircomechanical testing, colony boundary ...
متن کاملA numerical model for the description of the lamellar and massive phase transformations in TiAl alloys
A phenomenological modelling approach has been developed to describe the massive transformation and the formation of lamellar microstructures during cooling in binary g titanium aluminides. The modelling approach is based on a combination of nucleation and growth laws which take into account the specific mechanisms of each phase transformation. Nucleation of massive and lamellar g is described ...
متن کاملThe Role of Interfaces in Deformation Twinning of Lamellar TiA1/Ti3A1Crystals
The role of intakes in deformation twiming of Iamellar TiAl (ywl~l (a*) crystals creep deformed at an ekvated temperature have been investigated. Since the multiplication of lattice dislocations within both y and etzlamellae is very limited as a result of a refined lamekr microstmture, the gliding of interfheii dislocations on both y/a2 and y/y interfaces (i.e. interface sliding) becomes an imp...
