Abstract
The deformation behaviour of binary Ti-Al model alloys has been observed in respect to nucleation, propagation and growth of twins, specifically the interaction of slip and {1 0 -1 2} tensile twins. The area fraction of twins increases by trend from Ti-0Al to Ti-4Al but significantly reduces to Ti-6...

| Abstract: |
The deformation behaviour of binary Ti-Al model alloys has been observed in respect to nucleation, propagation and growth of twins, specifically the interaction of slip and {1 0 -1 2} tensile twins. The area fraction of twins increases by trend from Ti-0Al to Ti-4Al but significantly reduces to Ti-6Al. The lattice strain evolution during compression was measured using in-situ neutron diffraction and decreases from Ti-0Al to Ti-4Al but increases to Ti-6Al. The twin activity in hcp Ti behaves as expected from fcc materials until 4 wt.% Al concentration, but it is believed that short or long range ordering reduces the twin activity in Ti-6Al. |
