  "textContent": "Researchers at Skoltech conducted a comparative study of two techniques for evaluating mesoscale residual stresses in the aerospace alloy VT6 (Ti-6Al-4V) used to manufacture fan and compressor blades in aircraft engines. The study, published in the journal Measurement, demonstrates how combining gallium (Ga⁺) and xenon (Xe⁺) ion beams within the FIB-DIC (Focused Ion Beam—Digital Image Correlation) method enables reliable measurement of residual stresses in the critical mesoscale range from 0.05 to 0.5 mm.",
