The Debye-Waller factors (DWFs) of Co and Ti atoms in Co3Ti have been obtained by quantitative convergent-beam electron diffraction (QCBED). They are BCo = 0.20-0.24 and BTi = 0.41-0.43 Å2 in Co3Ti at room temperature. A modified simulated-annealing algorithm and its parallel algorithm were employed to obtain reliable results efficiently.
