The different factors that affect the Young's modulus such as the phase's stability, role of alloying elements, plastic deformation, and texturing are discussed.
Among the other mechanical properties, the low Young’s modulus alloys has been given a special attention recently in order to avoid the occurrence of stress shielding after implantation [2].
Young’s modulus change with phases stability It is well known that the Young’s modulus as well as some other mechanical properties change according to the type of the phases existing in the alloy [5].
(1) Some other elastic properties such as Poisson's ratio, anisotropy value, etc., can also be derived.
Texturing in the phases by sever plastic deformation of b-Ti alloys results in anisotropy of its properties including the elastic properties.

In the H-beam rolling process, the deformations and temperature field of workpiece significantly influence the mechanical properties due to the change of product microstructure.

Introduction The mechanical properties of the metal welded seal are strongly affected by the structures of the wave.
The shape of the bellows largely affects the welded metal bellows mechanical characteristics and technical targets.
All the other information was obtained locally and the cells communicated each other via diffusion of local factors.

Considering the progress of crack evolution, the depth and the location of geometrical imperfection were critical factors in determining the mode of crack initiation and propagation.
Recently, concentrations were placed on the numerical study of mechanical behaviors of DP steels.
It turned out that initial geometrical imperfection severely affected the overall ductility and failure mode of the DP590 steel.

An appropriate alloy composition allows to control the structural properties of the solidifying weld metal.
Several tests showed that the generation of nanoscale structures in the hardfaced coatings allows the improvement of mechanical properties, wear resistance and corrosion resistance.
Introduction The special nanoscale structure of nanophase materials yields exceptional mechano-physical properties, e.g. superelasticity at low temperatures, very high strength and ductility [1-4].
Fig. 4: Microstructure of the newly developed FeCrVB coating: a) light-microscopical record, b) SEM micrograph The mechanical properties of eutectic structures are mainly affected by three factors: Firstly, the type and the volume content of the hardphases, which determine the hardness and the wear resistance of the coating, secondly, the properties of the matrix, upon which the coating's ductility is a b a b 100µm depending, and thirdly, the proper interaction between matrix and hardphases.
The net structure and the high hardphase content improve the mechano-physical properties of the deposition-welded coatings.

Co-deposition was achieved at moderate temperatures in order to maintain the substrates` mechanical properties.
Important factors that affect the efficiency of the conventional steam power plants are the temperature and the pressure of the input steam to the turbine.
These techniques require high temperatures and/or longer times, which limits their use to substrates that can be exposed to high temperature without degradation of their mechanical properties [23].
Therefore CVD-FBR potentially is an important alternative for the deposition of Al-coatings on ferritic steels, since this technique allows the conservation of microstructure and mechanical properties of these types of materials.
Some comments are needed on the expected lifetime of such coatings, and the factors expected to influence the lifetime.
