Pure Cu single crystals irradiated at room temperature to low doses with 590MeV protons have been deformed in situ in a transmission electron microscope in order to identify the basic mechanisms at the origin of hardening. Cu irradiated to 10(-4) dpa shows ...
We have fabricated three-quarter ring structures on silicon nitride membranes for magnetic domain imaging using Lorentz electron microscopy. The ring structures have linewidths of 100, 250, 350 and 700 nm, and outer diameters of 1.65 mu m. Using the Foucau ...
The effects of neutron irradiation on the mechanical properties of welded joints made of austenitic stainless steels have been investigated. The materials are welded AISI 304 and AISI 347, so-called test weld materials, irradiated with neutrons at 573 K to ...
We study the state of a nanometric helium bubble in bcc-iron as a function of temperature and He content using atomistic calculations. It appears that up to moderate temperatures the Fe lattice can confine He to solid state, in good agreement with known sol ...
Reversible martensitic phase transformations in a partially disordered Ni-Al alloy within the composition range from 60 to 65 at. % of Ni are investigated using molecular dynamics simulation. During a complete temperature cycle a wide hysteresis in enthalp ...
Tungsten-iron alloy was produced by electrodeposition. The electrodeposited alloy (15 at.% W) possesses a two-phase composite microstructure, containing a nanocrystalline phase of distorted BCC structure with a grain size between 50 to 150 nm and an amorph ...
Small dislocation loops formed from self-interstitial atoms (SIAs) are commonly found in irradiated metals. These defects significantly influence the mechanical properties of the materials. Atomistic simulations are used to describe nanometric circular dislo ...
