| Popis: | X-ray and neutron diffractometry and inelastic neutron scattering studies on a set of cast ferritic iron-chromium alloys containing boron indicate that the dissolved boron is present interstitially rather than substitutionally within the α-Fe,Cr matrix. Inelastic neutron scattering spectra of the alloys may be interpreted in terms of the phonon dispersion curves for α-Fe. These spectra show small shifts in the frequencies of particular phonons, indicative of lattice disruption by the presence of interstitial atoms. These results were subsequently confirmed by internal friction measurements. |
