Despite these efforts, development of gas turbines reached the limits of the mechanical performance of blade materials.
The purpose of the TMF test on variations of fatigue life is to observe the change in mechanical properties of materials due to damage in TMF.
Also, an indentation test was conducted in order to observe the change of mechanical properties of materials following damage by TMF.

The proposed model for wear calculation is based on the application of theories from several branches of science to the description of 3D surface micro-topography in accordance with random field theory, assessing the material’s physical and mechanical characteristic quantities, substantiating the regularities in creation of material particles separated during the wear process and taking into consideration definite service conditions of fittings.
Thus the number of cycles of material destruction can be determined when knowing the material fatigue destruction parameters (N0, m, σ-1), standard deviation (σ), surface roughness parameters (RSm1, RSm2, c) and material elasticity modulus (E).

It is well known that properties of most cellular structures are depended on the mechanical properties of cell materials, foam relative density, and foam microstructures.
Constitutive Relations of Cell Material Most polymers carried loads in short time and at normal temperature could be treated as hyperelastic materials.

This, therefore, is the driving force for the search for new materials presenting increasing hydrogen storage capacities.
However, hydrogen solubility in many crystalline materials is usually very low [6].
In amorphous materials there is no long-range order, but there is evidence that hydrogen occupies the interstitial sites in short range ordered regions [8].

Introduction Ni-Mn-Ga ferromagnetic shape memory alloys (FSMA) are a potential new class of actuator materials able to respond at higher frequencies (at least 300 Hz) with comparable strains (up to 6 %) in a moderate field (below 1 T)[1].
Magnitude of the strain depends on the values of several critical material parameters, most importantly the martensitic transformation temperature (TMart), Curie temperature (TC) and saturation magnetization (MS)[2].

The modulus and internal friction directly related to the detail structure of materials are worth further investigating.
