List <strong>of</strong> Figures xii<br />
4.18 (a) A schematic show<strong>in</strong>g the width between <strong>Ag</strong> <strong>and</strong> <strong>Ni</strong> (111) planes at<br />
the <strong>in</strong>terface. (b) The <strong>in</strong>terface width for <strong>Ag</strong>/<strong>Ni</strong> <strong>and</strong> <strong>Ni</strong>/<strong>Ag</strong> <strong>in</strong>terfaces.<br />
The mean (111) d-spac<strong>in</strong>g, 0.2197 nm, is <strong>in</strong>dicated by the horizontal l<strong>in</strong>e.<br />
(d111,<strong>Ag</strong> = 0.23592 nm, <strong>and</strong> d111,<strong>Ni</strong> = 0.20345 nm). .............118<br />
4.19 Schematic show<strong>in</strong>g the method by which SUPREX treats gradients <strong>in</strong> the<br />
out-<strong>of</strong>-plane d-spac<strong>in</strong>g. ............................119<br />
4.20 High-angle x-ray diffraction peaks for the � = 3.2nm(a) <strong>and</strong> � = 5.9nm<br />
(b) <strong>Ag</strong>/<strong>Ni</strong> multilayers. The <strong>in</strong>tensity axis is on a logarithmic scale, <strong>and</strong> the<br />
data taken at E = 8320 eV is <strong>of</strong>fset above the E = 8020 eV data. The<br />
circles are the measured <strong>in</strong>tensities, the solid curve is the fit for the stra<strong>in</strong><br />
gradient model, <strong>and</strong> the dotted curve is the best fit when stra<strong>in</strong> gradients<br />
are disallowed. The order <strong>of</strong> the reflection is <strong>in</strong>dicated above the peak. . . . 119<br />
4.21 Calculated {111} d-spac<strong>in</strong>g pr<strong>of</strong>iles for the � = 3.2nm(a) <strong>and</strong> 5.9nm(b)<br />
<strong>Ag</strong>/<strong>Ni</strong> multilayers. The results <strong>of</strong> Jaszczak et al. for their theoretical multilayer<br />
are provided <strong>in</strong> (c) [113]. The vertical dashed l<strong>in</strong>es are the stra<strong>in</strong>-free<br />
d-spac<strong>in</strong>gs for the bulk phases. ........................120<br />
A.1 Diagram show<strong>in</strong>g the relationship between the sample coord<strong>in</strong>ate system,<br />
S, <strong>and</strong> the laboratory coord<strong>in</strong>ate system, L. .................146<br />
B.1 The focus<strong>in</strong>g circle. ..............................156<br />
D.1 The ratio <strong>of</strong> ɛ ′ 33 /ɛ′ D.2<br />
11 <strong>in</strong> the Vook-Witt model. .................172<br />
The biaxial modulus <strong>in</strong> units <strong>of</strong> 100 GPa us<strong>in</strong>g the Vook-Witt model. ....173<br />
D.3 The maximum resolved shear stress on the (111) slip plane given <strong>in</strong> GPa<br />
us<strong>in</strong>g ɛ ′ 11 = 0.704%. .............................174
