Swelling of neutron-irradiated 85Ni-15Cr at 400 to 650/sup 0/C
Technical Report
·
OSTI ID:6359261
The binary alloy 85Ni-15Cr swells during neutron irradiation in a manner quite unrepresentative of either Fe-Ni-Cr ternary alloys or pure nickel. Chromium additions appear to depress void nucleation in nickel but also appear to suppress the tendency of nickel to saturate in swelling at high exposure. Below a transition temperature somewhere in the range 538/sup 0/C < T < 593/sup 0/C the swelling is quite insensitive to irradiation temperature. Above the transition temperature the swelling behavior is more complex. At these higher temperatures the alloy densifies at low fluences, which is also indicative of the possible occurrence of long or short-range order. The swelling transition temperature also appears to coincide with the critical temperature for order-disorder transformation.
