Thin film samples of molybdenum were electron-beam evaporated at 80 K in a 6.6×10-4 Pa partial pressure of nitrogen and subsequently analysed for structure, superconductivity and crystallization behaviour. X-ray diffraction of as-deposited samples showed a typical amorphous structure and fcc and bcc phases upon heating. A superconducting transformation at 7.0 to 7.2 K was detected by the resistivity technique. Isothermal DSC scans obtained for a range of temperatures were calibrated and integrated to produce transformed volume (x)-time data. All plots of In [-In (1-x)] against Int have two linear regions with slopes ofn1?3.6 for 02? 2.0 for 0.72N-fcc phases in the X-ray patterns of the crystallized samples is discussed. Possible patterns of simultaneous or successive modes of nucleation and growth, including combinations of varying nucleation rates, different dimensionals of growth, and interfacial and diffusion controlled growth, are considered. |
