For these materials the strain-rate sensitive properties are particularly important, as well as the definition of models describing that behaviour.
Also the ability to use efficiently these materials is dependent on the numerical simulation of impact loading for design purposes, for which the improvements in material models are important.

Introduction Studies of interactions between vacancies and solute atoms (alloying elements or impurities) in crystalline materials are motivated by the significance of such interactions for our understanding of many important physical phenomena (such as diffusion, ordering, or decomposition) which occur in the materials during ageing or due to irradiation.
Iron-based alloys are undoubtedly the most important construction materials of our industrial society.
Steels have been used as nuclear materials, for example, for making pressure vessels of fission reactors.
Journal of Nuclear Materials 371, 37 (2007) ]; therefore they are considered as promising construction materials for the next-generation fission reactors as well as for the future fusion reactors.

In design of this system, several questions should be pay attention to as following: (1) in the design of optical system, lens with greater toughness and material that is able to bear rub should be selected; (2) The disperse angle is related to the focus of concave lens.

The brake disk and magnetic inductive disk are made of magnetic materials with high conductivity, and MRF is filled in the seal cavity where the brake disk, magnetic inductive disk and the coil surround, and the transmission shaft is made up of non-magnetic inductive material or resistance of magnetic treatment.
(2) Choice material for the core.
Because magnetic inductive disk, brake disk and core are made of materials with high permeability, and reluctance of the magnetic circuit mainly come from reluctance of MRF gap, and it is said that reluctance of other parts can be ignored in a certain extent; so total reluctance can be received for the magnetic circuit

Experiment Materials and equipments.
Before the experiment, the water in the raw materials must be removed by the water bath oven (drying the moisture content below 0.5%).Used the half solvent method (the mass ratio of the solvent and nitrocellulose is 0.2).
When put the raw material into cylinder, under the hydraulic press's strong extrusion (usually up to 20 ~ 30 MPa), the raw material through a certain mold and the nitrocellulose macromolecular forced in the direction of the flow material flow and regularly arrange.
