Irradiation-induced spinodal decomposition in alloys

摘要: Abstract Studies of homogeneous phase transformations induced by irradiation are aimed at developing materials for nuclear applications and understanding basic mechanisms decomposition. Spinodal decomposition, one the major modes separations, electron is investigated with respect to mechanism confirmation its inducement a large increase in coherent spinodal temperature. The decomposition successfully clarified analyses modulated structure using theory temperature up chemical limit under shown be due relaxation strain associated structure. process through high resolution microscopy. Interstitials vacancies produced accumulate spatially possessing definite wavelength. elastic interaction between fields around point defects themselves coherency maintained compositional fluctuations spatial modulation. It emphasized that periodic distribution excess contributes remarkably without destruction atoms, resulting
