Deformation behavior of HCP Ti-Al alloy single crystals

“…[3,4] At 77 with the earlier measurements of Reed-Hill on polycrystal-K, a small volume fraction of thin {1012} twins were formed line zirconium. [17] At 1000 K, the basal-slip lines became with ͗c ϩ a͘ accommodation slip in the matrix, similar to even better defined. that shown in Figure 15.…”

Microstructural features of rolled Mg-3Al-1Zn

“…The strain and accommodation kinks associated with the secondary "internal" twin change the apparent habit of the initial twin. [14,15] It has been suggested that these factors can cause the double twin to end up parallel to a plane, [15] which is inclined 7.3 deg to the original plane. Twins parallel to these planes were therefore considered in the present analysis.…”

“…The mechanism of double twinning, in which twins form in the interior of twins, has received considerable attention in single-crystal and pure Mg literature, [14,15] particularly in regard to the formation of compression bands. [3] In our previous EBSD analyses, we observed boundaries with misorientation angles and axes consistent with the operation of this mode in pure Mg. [16] However, in general, identification of these twins by EBSD analysis was hampered by the difficulty in obtaining diffraction patterns from the interiors of twins suspected to be of this type.…”
