A reliable two-stage carbon replica technique has been developed to extract precipitates from zirconium alloys. Using this technique, all precipitating phases can be extracted from Zircaloy-2, Zr-Cr-Fe, and Zr-Nb-Fe alloys. Precipitate identification

The technique for extracting second-phase particles from steels onto a carbon support film for analysis in the transmission electron microscope (TEM) has been in continuous use since its development by Bradley, nearly 30 years ago. However, the avail

The composition of two commercial rail steels (1% Cr and Cr-Cb) were modified by addition of vanadium and nitrogen. The microstructures and mechanical properties of the steels were determined. The results indicate that addition of 0.1% vanadium to th
