Features of structure formation of the nickel-beryllium and copper-beryllium alloys during aging under loading

Using diffraction methods of electron microscopy of thin foils the effect of compressing uniaxial stress has been studied on the aging process of the Ni-Be and Cu-Be alloys (tempering under load). It has been found that tempering under load results in a substantial change in the decomposition process; the effect of external loading stipulates for the nucleation of second phase particles of a certain orientation; with the formation of particles of the same orientation a new type of their spatial distribution is observed, as well as the change in the character of elastic distortions field around the precipitated phase nucleation
