COMPLEX INVESTIGATION OF EN Ni-P METALLIC GLASSES HAVING ANOMALOUS BEHA VIOR DURING LONG TIME ISOTHERMAL HEAT-TREATMENT

Abstract

An EN Ni-P layer consisting of two metallic glass components were examined after a short-time pre-heat treatment at 200°C, followed by a 5OOO-hour heat treatment at 160°C, then a 5-year relaxation at room temperature. X-ray diffraction, DSC, AES, and micro-hardness measurements were used in the study. Our only surprising experience was that the metallic glass recrystallized fully only during the room-temperature relaxation.
