Status of the lanthanides and actinides in the periodic table

In extended discussions and correspondence with Ekkehard Fluck, the author was made aware of a problem with the Periodic Table, i.e., which element should be shown in the main table as the representative of the lanthanide series and the actinide series. In earlier discussion, he came to the conclusion that lanthanum and actinium are not the elements which should appear, but rather lutetium and lawrencium are more appropriate for inclusion in their place. This paper will attempt to justify the r… more

Softening of Young's modulus of polycrystalline Nb/sub 3/Sn

Ultrasonic measurements show that the shear modulus (C/sub 11/-C/sub 12/)/2 softens dramatically as single crystals of Nb/sub 3/Sn approach the martensitic transition near 50K. It is expected that Young's modulus of polycrystals will olso soften, but previous ultrasonic measurements, which suffer from severe damping, fail to show the expected effect. We have measured Young's modulus of polycrystalline Nb/sub 3/Sn between 4.2K and 300K by static beam deflection methods, and observe marked soften… more

Strength of irradiated graphite: a review

Experimental data on the mechanical strength of nuclear graphite subjected to fast neutron irradiation are reviewed. At fluences below the turnaround point, the mean tensile, flexural, or compressive strength, S, increases over the unirradiated value, S/sub 0/, in a manner related to the irradiation-induced change in Young's modulus, E: S/S/sub 0/ = (E/E/sub 0/)/sup K/. The exponent, k, takes a value between 0.5 and 1, depending on the graphite grade, the irradiation temperature, and the method… more

Irradiation effects on the mechanical properties of composite organic insulators

Four kinds of cloth-filled organic composites (filler: glass or carbon fiber; matrix: epoxy or polymide resin) were irradiated with 2-MeV electrons at room temperature, and were examined with regard to the mechanical properties. Following irradiation, the Young's (tensile) modulus of these composites remains practically unchanged even after irradiation up to 15,000 Mrad. The shear modulus and the ultimate strength, on the other hand, begin to decrease after the absorbed dose reaches about 2000 … more
