Project summary

Technical Approach

The main idea of the concept of a diagnostic complex to monitor the heterophase processes in "IN SITU" is matching the measurements of phase and element composition of solids as well as the composition of a medium, gas or liquid, interacting with them.

The first stage of the work shall include a series of experiments on a simultaneous use in pairs of the devices out of the following ones available in Technocentre "LT" RDIPE, namely: laser ernfcsecixojNesined for anelement analysis, Raman-spectrometer designed for a phase analysis and CARS-spectrometer designed for monitoring gas composition. Measurements to be conducted shall be duplicated by conventional methods of material-studies and gas-analysis.

Upon development of the methodology, a series of experiments shall be conducted to investigate into "IN SITU" interaction between a number of metals and alloys on the one hand and various gas media on the other hand within a wide range of temperatures to create a necessary data-base and adequate general software.

Expected Results

In consequence of the works to be conducted under the project it is expected:

  • to manufacture a pro totype of a versatile laser diagnostic complex for a flexible monitoring of heterophase processes "IN SITU" which has the following main technical characteristics:

-sensitivity of gas analysis Ivpm;

-sensitivity of element phase analysis 10-3%;

-sensititvity of phase analysis of phase composition of surface 1%;

-film thickness at phase analysis from 100 run to 10 mn;

-sizes of crater at element analysis of a solid phase 10 -50 mm;

-penetration depth during layer-by-layer element analysis up to 1 mm;

-step of layer- by-layer analysis 10 mm;

-time from 1s;

-temperature in working space of autoclave up to 1300 K;

-pressure in working space of autoclave up to 20 MPa.

-registered admixtures in different phases are C, S, Mg, Cu, W, Mo, Zr, Ca, Na, Fe, Cr and etc. Theoretically, all elements of Periodic system are registered. Besides, a wide spectrum of gas components is analyzed;

  • to elaborate general software to control the complex and process experimental data;
  • to elaborate methodology to flexibly monitor "IN SITU" the processes of interaction between solids on the one hand and liquids and high-temperature gases on the other hand;
  • to conduct a series of experiments using the complex "IN SITU" to investigate into the interaction between various chromium-nickel steels and alloys on the one hand and high-temperature helium medium with various concentrations of chemically active admixtures, in particular oxygen, nitrogen and water vapours, on the other hand;
  • to create a data-base for spectra,characterizing the kinetics of Interaction processes in high-temperature heterophase systems.
