In the elastic range of deformation, most FCC metals (except Al) exhibit strong elastic
anisotropy.
The lattice strains in the longitudinal direction, el//,hklε , are proportional to the applied macro-stress, σM: hkl M el //,hkl E σ ε =
The transverse strains, el,hkl ⊥ε , for an isotropic elastic solid subjected to uniaxial loading are represented by M hkl hkl el ,hkl E σ ν ε −=⊥
Following the approach of Gnäupel-Herold et al. [11], we solved the reciprocal problem in determining the best values for single-crystal elastic constants, which fit the experimentally determined data in the frame of Kröner model.

After temper-rolling, YP-El of all of the sheets decreased.
After aging, YP-El of steel C22 and C45 reappeared.
Takeda et.al. 5) reported that ky of extra low carbon steels water-cooled from annealing temperature were from 100 MPa・μm-1/2 to 600 MPa・μm-1/2.
Funakawa et.al. 7) reported that ky reached maximum 600 MPa・μm-1/2 in the air-cooled steel sheet after annealing with the solute carbon of 13ppm.
Steel C16 had enough solute carbon to make Cottrell atmosphere, but YP-El did not reappear.

Abstract: We study the initial growth of 10 monolayers (MLs) of GaSb on a (001) GaP substrate.
Since the initial works of Chang et al. [3], AlSb/InAs heterostructures exhibiting electron mobility higher than 30 000 cm2.V-1.s-1 have been demonstrated on mismatched GaAs or InP substrates using a GaSb or an AlSb metamorphic buffer layer [2, 4-5].
Even if these values are lower than the best ones reported on GaAs or InP [4-5], they are similar to the ones reported by Lin et al. [14] using a ten times thicker buffer layer for a similar system.

For instance, Storasta et al. assume a pseudodonor character of the the D1 defect, that is associated
with a hole trap at 0.34 eV above the valence band [28].
Furthermore, Kimoto et al.

Photon emission around 1.8 eV has also been reported in earlier work [21, 23, 29] measuring thermal stimulated luminescence (TSL) and photoluminescence attributing it to aluminum (Al) as a hole trap or the PbC center.
Different luminescence measurements methods (L) such as photoluminescence (PL), photoexcitation (PE), thermally stimulated luminescence (TSL), thermoluminescence (TL), electroluminescence (EL), chathodoluminescence (CL) and photo stimulated tunneling (PST) are used.
