Recrystallization reaction kinetics and texture studies of a 50 iron 50 nickel alloy

Abstract

Recrystallization rate curves for a 50 iron 50 nickel alloy are plotted from data obtained using an X-ray spectrometer, and an activation energy is calculated for the reaction. A multiple crystal orientation is found for the as-rolled material, and the cube texture when recrystallized in the range of 500° to 600°C. It is well established that the directions of easiest magnetization in a single crystal of alpha iron are of the form , while for nickel the corresponding directions are of the form . However, when iron is added to nickel the directions persist as the easiest for magnetization until about 25 pct iron has been reached. In alloys containing more than 25 pct iron the directions of easiest magnetization change from to .
