Zircaloy-based materials with constant tin content, a constant sum of Fe and Cr content, and different Fe/Cr ratios were manufactured from small ingots (6 kg) by forging, {beta}-quenching, hot rolling, and cold rolling with two different annealing sequences resulting in two accumulated annealing parameters. To study the effect of Ni, chromium was substituted by nickel in one alloy. As a reference material standard, ASTM Zry-2 was manufactured in a similar way. These materials were examined for precipitate size by TEM and for their out-of-pile corrosion behavior in 400 C steam up to 319 days and in 500 C steam up to 24 h in a static and in a refreshed autoclave. Furthermore, samples made from these alloys were irradiated in a commercial BWR for two years. Results of the test are given.
