In undeformed materials GBM which refers to the movement of a gb separating two grains relative to the material that makes up those grains will be driven by grain boundaries energy reduction while in deformed polycrystalline materials GBM will additionally be driven by strain energy (i.e. built up of lattice defects during deformation) reduction.
Since our observations are consistent with those reported for other materials e.g.
NaCl [5], we suggest that they are a common and general occurrence in crystalline materials.
Our observations are consistent with those reported for deformed-then-annealed NaCl [6], we therefore suggest that they are a general occurrence in crystalline materials.

Introduction Bulk metallic glasses (BMGs) have unique physical, chemical and especially mechanical properties [1], which make them as potential new engineering materials.
However, it is known that the materials’ stability in the environmental conditions is an important property that must be considered before they are used.

Introduction The achievements of material science such as the new high-tech materials (both homogeneous and heterogeneous) make it possible to increase significantly the strength and stiffness of structures designed.
All existing structural materials contain different inter- and intra-component defects (cracks, delaminations, etc.).
It is equally true for both, homogeneous and heterogeneous materials.

Electrocatalysts was produced from precious metals, non-precious metals, and carbon-based materials [7], [8] Pt is the most widely utilized electrocatalyst based on a precious metal for oxygen reduction reactions because of its high and stable electrocatalytic activity.
Carbon-based materials such as carbon aerogel have high catalyst activity and environmentally friendly [9].

Most materials have two energies where the dynamic charge balance is obtained; these are typically referred to as E1 and E2.
For most materials E1 is at energies not suitable for SEM operation and also does not present a stable operating condition [16].

The vibration will cause the body of material fatigue, will increase the probability of the unit appears damaged, and will cause the turbine speed dropped significantly reduce the output power.
The data showed that the vibration will cause the body of material fatigue, will increase the probability of the unit appears damaged, and will cause the turbine speed dropped significantly reduce the output power, Therefore, the wind turbine vibration monitoring of wind turbine operation provide a basis for design reasonable machine, improve efficiency, and to prevent unit damage.
The data showed that the vibration of the vibration will cause the body of material fatigue, will increase the probability of the unit appears damaged, and will cause the turbine speed dropped significantly reduce the output power.
