RECOVERY AND RECRYSTALLIZATION OF ZIRCONIUM AND ITS ALLOYS. PART 1. SPECIMEN COMPOSITIONS, COLD WORKING, HEAT TREATMENT, AND SURVEY OF THE LITERATURE
Zirconium, Zircaloy-2, vacuum-melted Zircaloy-3, and argon-melted Zircaloy-3 were cold worked to levels of 10, 25, and 50% preparatory to conducting recovery and recrystallization annealing studies. A uniform penultimate grain size was established for each material prior to cold working. Annealing studies were made in three atmospheres, air, helium, and vacuum, to establish the effect of contamination on properties. The results of Rockwell G hardness and electrical resistivity measurements are reported on the cold-worked material as are corrosion tests in 360 deg C water. An extensive survey of the literature dealing with recovery and recrystallization is presented with particular emphasis on zirconium and zirconium alloys. (auth)
