• The critical voltages in ordered and disordered states of Ni_3Fe and FeCo alloys were measured for the systematic reflections without superlattice reflections. A small increase in the critical voltage was observed on ordering for the 111 systematic reflections of L1_2 type Ni_3Fe. The temperature factors and the Debye temperatures were evaluated from the measured critical voltages. The changes on ordering in the temperature factors and Debye temperatures were in reasonably good agreement with those derived by X-ray investigation and elastic constants. It is shown that the change in the critical voltage of Ni_3Fe is mainly due to the change in the thermal mean-square displacement of atoms. No obvious change in the critical voltage on ordering was detected for 110 systematic reflections of B2 type FeCo.
