Measurement of Debye-Waller factors in Co3Ti by quantitative CBED
1Electron Microscopy Laboratory, School of Materials Science and Engineering, Tsinghua University, Beijing, People's Republic of China.
Abstract:
The Debye-Waller factors (DWFs) of Co and Ti atoms in Co3Ti have been obtained by quantitative convergent-beam electron diffraction (QCBED). They are B(Co) = 0.20-0.24 and BTi = 0.41-0.43 A2 in Co3Ti at room temperature. A modified simulated-annealing algorithm and its parallel algorithm were employed to obtain reliable results efficiently.
