TL;DR: In this paper, the authors derived relationships between anisotropy of in-reactor creep and growth of zirconium alloys with their crystallographic texture and grain shape, and concluded that growth occurs primarily by partitioning of interstitials to dislocations or prismatic loops and vacancies to grain boundaries.

TL;DR: In this paper, two SS-Zr compositions have been selected as baseline waste form alloys: (a) stainless steel-15 wt% zirconium (SS-15Zr) for stainless steelclad fuels and (b) Zr-8wt% stainless steel (Zr−8SS) for Zircaloy-clad fuels.

TL;DR: The mechanism of grain refinement by the addition of small amounts of titanium, molybdenum, zirconium, tungsten, and chromium to aluminum was investigated in this article.
Abstract: The mechanism of grain refinement by the addition of small amounts of titanium, molybdenum, zirconium, tungsten, and chromium to aluminum was investigated. The results indicate that the grain refinement is caused by the peritectic reaction which, by transforming the intermetallic compound into crystals of aluminum solid solution, seeds the melt with nuclei above the freezing point of aluminum.

TL;DR: In this article, a new Cu-based bulk glassy alloys with high glass-forming ability and good mechanical properties were formed in Cu-Zr-Ti-Be system.
Abstract: New Cu-based bulk glassy alloys with high glass-forming ability and good mechanical properties were formed in Cu-Zr-Ti-Be system. The glass transition temperature (T g ), supercooled liquid region defined by the difference between crystallization temperature (T x ) and Tg, ΔT x (=T x -T g ) and reduced glass transition temperature (T g /T l ) are 728 K, 50 K and 0.64, respectively, for the (Cu 0.6 Zr 0.3 Ti 0.1 ) 92.5 Be 7.5 and 720 K, 42 K and 0.64, respectively, for the Cu 54 Zr 27 Ti 9 Be 10 alloy. The use of the 7.5%Be and 10%Be alloys has enabled us to form glassy alloy rods with diameters up to 5 mm. The bulk glassy 10%Be alloy exhibits high tensile fracture strength of 2450 MPa and Vickers hardness of 710, in combination with Young's modulus of 146 GPa, compressive fracture strength of 2500MPa and compressive elongation of 3.5%. The tensile strength level is the highest among all bulk metallic glasses and hence the new Cu-based bulk glassy alloys have significant importance in basic science and engineering aspects.

TL;DR: A statistical TEM investigation of this mechanism has been performed on neutron irradiated recrystallized Zr alloys tested at 350 °C in this article, where it was shown that irradiation leads to a higher increase of critical resolved shear stresses for prismatic and pyramidal slip systems than for basal slip system.
