The possible influence of order-disorder transformations on the swelling of 85Ni-15Cr nichrome alloy

摘要: Abstract The binary alloy 85Ni-15Cr swells during neutron irradiation in a manner that is quite unrepresentative of either simple austenitic alloys or pure nickel. nickel-chromium system known to exhibit ordering out reactor and this was used test the concept which develop order lower swelling rates. When data are compared ion irradiations conducted by Hudson Ashby on Ni-Cr alloys, it shown chromium additions appear depress nickel initially but also suppress tendency for saturate at high exposure. Below transition temperature near 550°C relatively sluggish insensitive temperature. Above behavior more complex typical alloys. thought be related critical order-disorder transformation.
