Translation Stage

A laboratory X-ray diffractometer devoted to thein situcharacterization of the microstructure of epitaxic thin films at temperatures up to 1500 K has been developed. The sample holder was built using refractory materials, and a high-accuracy translation stage allows correction of the dilatation of both the sample and the sample holder. The samples are oriented with respect to the primary beam with two orthogonal rotations allowing the registration of symmetric as well as asymmetric reciprocal space maps (RSMs). The association of a monochromatic primary beam and a position-sensitive detector allows the measurement of RSMs in a few minutes for single crystals and in a few hours for imperfect epitaxic thin films. A detailed description of the setup is given and its potential is illustrated by high-temperature RSM experiments performed on yttria-doped zirconia epitaxic thin films grown on sapphire substrates.

Experimental Apparatus

Residual stress states, induced by milling in a die cast aluminum alloy component, have been determined by means of X-ray diffraction. Samples have been cut from an automotive engine sump, fabricated by pressure die-casting. The X-ray experimental apparatus has been calibrated by detecting stresses on a sample bent under imposed external deformations. Different samples (cut from the sump) have been tested after milling operations with each one characterized by different cutting speed, feed speed and depth of cut in order to evaluate their influence on the final residual stress state. Results have been analyzed taking into account surface morphologies after milling, as revealed by scanning electron microscopy.
