Influence of Second Phase Particles on Recrystallization in Fe-36Ni Alloy

Abstract

The influences of second phase particle in the size range 1 to 10 μm in Fe-36Ni alloys on recrystallization were investigated and the sample was cold-rolled with 50% and 80% cold rolling reductions, and annealed at 873K or 923K. Orientation measurements of grains have been made using electron backscattered diffraction in SEM (SEM-EBSD). The obtained results are as follows. (1) In case of the 50% cold rolling reduction, deformation zones with 5 μm width was formed near the second phase particle. (2) (110) orientation grain as the nuclei from the deformed structure was observed. (3) (123) orientation in the sample included second phase particles was formed around the second phase particle. And (115) orientation in the sample without second phase particles was formed around the second phase particle.
