Abstract:

Positron annihilation measurements, performed via Doppler broadening of the annihilation gamma photon energy distributions, have been effectively applied to follow age hardening, hydrogen embrittlement, dislocation generation during single crystal bending, phase transformations in steel, deformation of both samples containing precipitates and preprecipitates and the deformation of steel. The technique is nondestructive and sensitive to line and point defects, interfaces, and microvoids. Author
