Abstract

In the present work, it is experimentally found that rapid solidification enhances significantly the γ-FCC → ε-HCP transformation by generating a high density of ε-martensite embryo nucleating defects in a Co-20Cr alloy. Conclusive evidence based on X-ray diffraction determinations combined with SEM and TEM observations indicates that the formation of athermal ε-martensite is strongly influenced by rapid solidification conditions (i.e., up to 89.6 vol pct).
