In this study, real time measurement of the linear expansion of industrial material undergoing temperature change by using a computer-aided interferometric measuring technique with micrometer accuracy is attempted. Aluminum and copper were subjected to temperature change in the thermal expansion experiment unit (LETI-1) causing them to expand linearly. The fringe number in the interference symbol, which includes the information about linear expansion and temperature change were transferred to a computer via a data acquisition card, graphed by a program created in the LabVIEW environment, and the amount of linear expansion was detected in real time.

Oxidation of erosion products was studied by means of the Mössbauer spectroscopy and X-ray diffraction methods when the strip of stainless steel was cut with the laser. Different content of wustite and chromium doped magnetite Fe_{3-x}Cr_{x}O_{4} was found in the samples of erosion products depending on the place where the erosion products were collected in relation to the cutting slot. Conversion electron Mössbauer spectroscopy data showed that more magnetite was found at the surface while wustite distributes in the whole volume of particles of erosion products.
