Image of FIG. 1.
FIG. 1.

Schematic drawing used to define the rotation angles and in the laboratory coordinate system Li [ is the normal to the diffraction planes for which the spacing is measured by x rays] and in the sample coordinate system (1, 2, 3) (1 and 2 are contained in the sample surface and 3 is the normal to the surface).

Image of FIG. 2.
FIG. 2.

Schematic drawing to illustrate the triaxial state of stress model: (a) only the surface region is irradiated by the ion beam; (b) radiation defects induce a swelling of the irradiated region, which is associated to a hydrostatic stress; and (c) the lateral dimensions of the damaged layer are imposed by the undamaged part of the material beneath the damaged part, leading to the occurrence of a biaxial stress superimposed to the hydrostatic stress.

Lattice spacing vs for CSZ irradiated with Pb ions at fluences ranging from to . Lines are linear fits to the data.

Image of FIG. 7.
FIG. 7.

Variation of the hydrostatic and biaxial stress components in CSZ irradiated with Pb ions. Lines are fits to the data according to Eq. (11).

Tables

Table I.

Experimental stiffness and compliance of elastic constants of CSZ (see Ref. 20). The x-ray elastic constants and for the (531) plane are calculated from compliances with the Hill–Neerfeld model. The Poisson ratio and the Young modulus for the (531) plane are derived from x-ray elastic constants.
