Zirconium Alloys in Nuclear Applications

“…The usual oxygen content is in the range of 800 -1600 ppm and its purpose is to increase the yield strength by solution strengthening. A 1000 ppm oxygen addition increases the yield strength by 150 MPa at room temperature, (Armand et al, 1965). Oxygen is an a stabilizer, expanding the a region of the phase diagram by formation of an interstitial solid solution.…”
