An attempt was made to identify oxides on 0∼2.5 wt%Be-elinvars at 800°C and 1100°C in a dissociated-ammonia gas and in air. For this, electron and X-ray diffraction methods were adopted. An X-ray microanalyser and an optical microscope were employed complementally in the observation of the oxides. The results obtained are as follows;<BR>(1) BeO was formed selectively on the surfaces of 0.5∼2.5 wt%Be-elinvars heated in a dissociated-ammonia gas at 800°C and 1100°C for a few minutes.<BR>(2) On the surfaces of 1.2∼2.5 wt%Be-elinvars heated in air at 1100°C for 1 hour, BeO was formed predominantly.<BR>(3) The surfaces of 0∼1.2 wt%Be-elinvars exposed in air at 1100°C for 1 hour were covered with layer oxides—α-Fe2O3 (outer layer), spinel type oxide or (Fe, Ni, Cr)3O4 (inner layer).<BR>(4) A thin BeCr2O4 film, in the same condition as above, spread itself on the surface of 2.5 wt%Be-elinvar, in pores of which the patches of oxides with layer structures were dispersed.
