The Role of Austenite Grain Misorientation on Ferrite Nucleation in an Fe-Cr-Ni Alloy
The relationship between the misorientation of the austenite crystallites and the favoured sites for ferrite nucleation has been investigated. Ex-situ EBSD measurements were performed on an especially developed high purity ternary iron alloy with 20 wt.% Cr and 12 wt.% Ni with both austenite and ferrite present at room temperature to measure the misorientation between the austenite crystallites. The experimental results are compared to the nucleation models of Clemm and Fisher and Aaronson and co-workers.
