Defects in metal crystals. Progress report, May 1, 1975--April 30, 1976. [W--Re; Pt--Au; Mo--Ti]
Emphasis was on use of different irradiating species (300-700 eV Xe/sup +/ ions, 20-30 keV W/sup +/ ions, 20-30 keV Mo/sup +/ ions, and fast neutrons) to introduce both vacancies and interstitials in Mo, W, Au, Pt--(Au), W--(Re), Mo(Ti), Ni/sub 4/Mo, and low-swelling and commercial 316 stainless steels. The following are reported: (A) an in-situ field-ion microscope study of ion-irradiated tungsten and tungsten alloys (W-Re) (recovery in Stages I and II); (B) a review of Stages I to IV of irradiated or quenched tungsten and tungsten alloys by field-ion microscopy; (C) a review of field-ion microscope studies of the defect structure of the primary state of damage of irradiated metals; (D) an in-situ field-ion microscope study of the recovery behavior of ion-irradiated molybdenum in Stages I and II; (E) a field-ion microscope study of the recovery behavior of Stage II in ion-irradiated platinum-0.10, 0.62 and 4.0 at. percent gold alloys; (F) a new technique for focused-collision sequence range measurements; (G) atom-probe field-ion microscopy (improvements, results on W alloys, Mo alloys (Mo, TZM, Mo--Ti), low-swelling stainless steel alloy); (H) range of a focused collision replacement sequence in ordered alloys; and (I) interaction of self-interstitial atoms with impurity gas solute atoms in refractory metals. 11 fig, 5 tables, 37 references.
