“…Both results with and without the non-analytical term correction (LO-TO splitting) are presented. Li2TiO3 transforms toβ-Li2TiO3 above 575 K [5] with the monoclinic Li2SnO3-type structure, space group C2/c (15), lattice parameters of a = 0.50622, b = 0.87712, c = 0.97487 nm, β = 101.01°, and the unit cell contains 24 atoms [6], thus, the force constants were calculated in a super-cell containing 96 atoms. The Li burnup was modeled by the introduction of Li vacancies in the supercell (removing Li atoms).…”

OBJECTIVEDifferent HFIR irradiated ODS steels (MA957, 12YWT, PM2000) were uniaxial tensile tested in the hot cells. These materials were irradiated in the QST collaboration in various irradiation capsules including JP26 and JP27. Previously, Vickers hardness data on these steels was reported. Here, results from the tensile tests at room temperature (RT) and irradiation temperature (Tirr) are presented. The results revealed significant irradiation hardening in ODS steels for Tirr>400 °C and up to 500 °C The results are compared with literature and with HFIR irradiated RAFM steels to develop a detailed understanding of low temperature hardening-embrittlement (LTHE) in ODS steels. This report details the dose and temperature dependent hardening and loss of ductility of the studied materials.
