![]() ![]() It is predicted that this secondary phase separation occurred at a lower temperature than the first separation due to the slow cooling rate. These two regions were denoted α 2 while the region with the highest Zr concentration was denoted α 1. The full edition of the CrystalMakers Users Guide is now available directly from the. Points 5, 6, and 8 were placed over the slightly lighter darker regions within the α phase and yielded a higher concentration of Ti and slightly lower concentration of Zr. CrystalDiffract provides powerful x-ray or neutron powder pattern. β) but also further separation of the α (lighter) region into two distinct compositions. A Zeiss LEO scanning electron microscope scanning electron equipped with EDS was used to analyze the microstructure of the annealed specimen, see Table 1 and Fig. 2, Fig. 3, Fig. 4.ĮDS scans show that the annealing with slow cooling rate induced not one instance of chemical segregation into two regions either enriched or depleted in Zr (α vs. : CrystalDiffract User's Guide: 9780993232008: Palmer, David C: Libros. Half of the sample was wrapped in Ta foil to prevent leaching and annealed at 1200 ☌ for 24 hours in a Carbolite CTF 12 vacuum tube furnace, the sample was allowed to furnace cool at ∼2 ☌/min.

Additional peaks were suggestive of hexagonal closed packed (hcp) alpha as well as secondary bcc phases, these were studied in further detail following alternative heat treatment in the associated work by King et al. The primary body centred cubic (bcc) peaks were identified and smoothed using Lorentz peak fitting software PeakFit v4 and CrystalDiffract, see Fig. 1 for the fitted XRD peaks. ![]() XRD was performed using a Bruker D8 Discover X-ray diffractometer using copper K-α x-rays of wavelength 1.54 Å. The NbTiVZr sample was cut into a 1 cm diameter disk and polished. University of Wisconsin- Madison, Madison, USAĭ.J.M. Under special conditions, all the unit cells in the crystal diffract in phase. The resultant microstructure was analyzed using standard laboratory equipment. Hongyi Xu, in Reference Module in Materials Science and Materials. EDS: no standardsĪnnealed in vacuum furnace w/slow cooling rate (1200° C, 2 ☌/min)īulk arc melted samples of NbTiVZr were annealed at 1200° C and furnace cooled. XRD was performed using a Bruker D8 Discover X-ray diffractometer, SEM/EDS was performed using a Zeiss LEO scanning electron microscope Scribd is the world's largest social reading and publishing site.
