ABSTRACT:
Zircaloy 2 or 4 strip is heat treated in the beta range, followed by rapid cooling by passing the strip between a first and second roller pair, each roller pair having two oppositely disposed rollers gripping the strip. Each roller pair is connected to a source of an electric current so as to complete an electric circuit including the source, the roller pairs and the strip, which causes heating of the strip to the beta range. The strip is heated at a rate less than 40.degree. C./sec between 750.degree. and 1000.degree. C., held at 1000.degree.-1100.degree. for less than 2 minutes and cooled at a rate of at least 40.degree. C./sec between 1000.degree. C. and 600.degree. C.
