TL;DR: In this paper, a study was conducted to determine the response of disc bend test data to variations in the relative size of the spherical penetrator, receiver hole and specimen thickness, and it was found that load displacement data were most sensitive to thickness; yield load, maximum load and penetrator displacement to failure all increased to the greatest extent with increasing specimen thickness.

TL;DR: In this paper, the tensile and bulge tests were carried out on Ni, Au and stainless steel irradiated with D-T fusion neutrons from RTNS-II and showed a large increase in yield strength up to factors of 7 and a reduction of ductility down to 50% by the irradiation of 1.7 × 10 22 n/m 2.

TL;DR: In this article, the defect microstructures in various materials were compared with those introduced by irradiation with conventional control, and the strong influence of the transient lower temperature irradiation during the start-up of the reactor is obvious.

TL;DR: In this article, transmission electron microscopy was used to study La0.7Ca0.3MnO3 (LCMO) films grown on (0, 0, 1) surfaces of various (pseudo-) cubic substrates, MgO, SrTiO3, LaSrGaO4 and YAlO3.
