Structural Changes in a Model Alloy after Irradiation of Fe62M35Ti3 with Fast Neutrons and Isochronous Temperature Annealing

摘要

The experimental results of neutron diffraction studies of the crystal structure of the Fe_(62)Ni_(35)Ti_3 alloy after irradiation with fast neutrons and postradiation isochronous annealing are presented. It is shown that the structural state of the Fe_(62)Ni_(35)Ti_3 alloy for all external forces is determined by two competing processes: the creation or annealing of radiation defects and precipitation or dissolution of the metastable ?' phase Ni_3Ti.
