Web1 day ago · Due to this effect, the crystallographic texture of the as-welded condition may be partially regenerated after normalization heat treatment. Therefore, the observed fracture along the coarse-grained heat-affected zone might be due to the significant fraction of cleavage planes [46]. Further studies are planned to understand the microstructure ... WebApr 6, 2011 · The strain compatibility condition for the T 2 twin should be ensured at the expense of the slip transmission of the \( (112)[\bar{1}\bar{1}1] \) M1 system to the twin slip systems belonging to the \( [1\bar{1}0] \) TD crystallographic zone. The major condition for the slip transmission to occur from the matrix to the twin and further to the ...

The translational invariance of a crystal lattice is described by a set of unit cell, direct lattice basis vectors (contravariant or polar) called a, b, and c, or equivalently by the lattice parameters, i.e. the magnitudes of the vectors, called a, b and c, and the angles between them, called α (between b and c), β (between c and a), and γ (between a and b). Direct lattice vectors have components measured in distance units, like meters (m) or angstroms (Å). http://www.clay.uga.edu/courses/8550/millerindices.html
