Effect of iodine partial pressure on the iodine stress corrosion cracking behaviors of Zr-Sn-Nb alloy using the ring tensile test

In order to evaluate the effect of iodine partial pressure on the iodine stress corrosion cracking (I-SCC) behaviors of a Zr-Sn-Nb alloy, ring tensile tests were conducted at 350 °C and in atmosphere without iodine and with iodine partial pressure of 10 2 , 10 3 , and 10 4 Pa, respectively. Results...
