RESEARCH INTERESTS

 

Application of high resolution neutron diffraction for:

- investigation of residual stress, texture, phase content, microstress and particle size effects;
- residual stress studies in various engineering components, coatings, welded materials, widely used in nuclear power plant industry;
- calibration of non-destructive methods (ultrasonic and magnetic Barkhausen noise technique) for quantitative stress analysis;
- investigation of fatigue damage in austenitic steel due to cyclic load;
- residual stress studies in advanced materials (composites, functionally graded materials, etc.);
- investigation of material mechanical properties (elastic constants, thermal expansion coefficients and yield strength);
- residual stress analysis after various thermal and mechanical treatments.

Methodical researches:

- neutron diffractometer optimization and sample environment development;
- development of reverse time of flight (RTOF) technique;
- application of the new techniques (e.g. neutron transmission, positron annihilation) for materials investigation.
