Abstract

The 1980 literature review by D. P. Whittle and J. Stringer summarized a wide range of experimental results and proposed hypotheses regarding the reactive element effect. Reading this document in 2001 reveals exactly how far the study of the reactive element effect has come in the past 21 years. With the advent of advanced analytical techniques such as scanning transmission electron microscopy and secondary ion mass spectrometry (for detecting 18O tracers), many issues about RE effects on growth mechanisms and microstructure have been resolved. Emphasis now centers on the role of impurity elements (especially C and S) in conjunction with reactive element additions, the interfacial segregation and diffusion of RE ions, and the mechanical response of the substrate during oxidation. In several areas, there have been changes in the interpretation of results and there are several new sub-topics pertinent to the reactive element effect that were not covered in the 1980 review.
