Effect of combined addition of phosphorus and titanium on microstructural evolution in Fe-Cr-Ni alloys

Drastic influence of micro-alloying on Frank loop nature in Ni and Ni-based model alloys

“…162, 91191 Gif-sur-Yvette CEDEX, France and produce line dislocation networks involved in the nucleation and growth of voids [7,8]. Meanwhile, the microstructure (density and size of dislocation loops and voids) is affected by the addition of solutes and impurities (like oxygen) over a wide range of metal materials (fcc, body-centered cubic (bcc)) and even novel concentrated solid solutions [9][10][11][12][13][14][15][16]. Thus, it can be seen that dislocation loops play an important role in the microstructural evolution in the early stage of irradiation.…”

The effect of alloying elements on the vacancy defect evolution in electron-irradiated austenitic Fe–Ni alloys studied by positron annihilation

“…The size factor has the decisive effect on the character of the interaction between alloying atoms and point defects in the solid solution. In nickel and austenitic Fe-CrNi and Fe-Ni alloys, undersized impurity atoms (P, Si) interact predominantly with interstitial atoms [2][3][4][5], while oversized impurities (Ti, Nb) interact with vacancies [3,6,7]. The formation of stable low-mobility complexes of interstitial atoms or vacancies with impurity atoms increases the recombination of point defects and, hence, changes the formation kinetics of defect clusters.…”
