[On the ageing characteristics of commercial Elgiloy (author's transl)]

An age-hardening phenomenon in commercial Elgiloy was studied by means of resistivity, hardness and X-ray diffraction. The increase in hardness during ageing in the range 400-800 degrees C was accompanied by a pronounced increase in resistivity. The X-ray diffraction study showed that any precipitate was not taken place by ageing. The proposed mechanism of hardening during involves the segregation of solute atoms to stacking faults by the SUZUKI's chemical interaction mechanism.
