The Doppler broadened lineshape is measured as a function of temperature for iron and vanadium; vacancies produce a strong trapping effect in γ-Fe, but a weak effect in V. Threshold temperaturesT t for trapping are 1280±25 and 1370±30 K. Empirical linear relationships betweenT t , self-diffusion energyQ SD and monovacancy formation energyH 1v F are discussed and used to determineH 1v F values for γ-Fe and V. |
