Y2TiO5 and Y2Ti2O7 are very important materials for nuclear applications and hence, a complete understanding of their radiation response as well as their physical properties is highly desired. Molecular dynamics (MD) is one of the most efficient tech

The effect of displacement cascade on Y2Ti2O7 and Gd2Zr2O7 pyrochlores is studied using molecular dynamics simulations. A vast statistics of displacement cascades is generated and the damage is characterized using complementary techniques. It is show

We study the characteristics of displacement cascades in single crystal Y 2 O 3 using classical molecular dynamics. There are two possible ways to generate the cascades in yttria, using either the Y or the O atoms as the primary knock-on (PKA) atom.

We present a molecular dynamics study of radiation damage arising from nuclear collisions close to embedded yttria nanoparticles in a bcc Fe matrix. The model assumes a perfect body-centred cubic (bcc) iron matrix in which yttria nanoparticles are em

Y 2 O 3, Y 2 TiO 5, and Y 2 Ti 2 O 7 precipitates are the key ingredients of the oxide dispersion strengthened (ODS) steels, and a study of their irradiation behavior and amorphization resistance is very important for the nuclear industry. We perform

The effect of displacement cascade on Fe-Y2TiO5 bilayer is studied using classical molecular dynamics simulations. Different PKA species – Fe, Y, Ti and O – with the same PKA energy of 8 keV are used to produce displacement cascades that encompas

Molecular dynamics simulations are carried out to understand the role of different conditions affecting the displacement cascade characteristics in the vicinity of a tilt/twist GB. It is shown that while GB affects the survival of point defects, the
