With ring-ball test sidewalls of samples are only little affected by the centrally applied bending force.
It should be mentioned that it was not our intention to determine the “best” grinding wheel but to find out how the differently ground silicon wafer surfaces behave in terms of their mechanical properties.
Here, we conclude that the thin silicon material exhibits its intrinsic material properties and the fracture strength is defined by bulk behavior of a non-distorted single-crystalline silicon lattice.
Additional stress-relief processes after grinding improve fracture strength significantly by a factor of 6 to 15.

The electron-atom ratio (e/a) dependence of the appearance of the lattice modulation and physical properties in β-phase Ti-xNb alloys (x = 28, 30, 34 and 40) were investigated by using some physical properties measurements, compressive test and transmission electron microscope observations (TEM observations), focusing on the β-phase stability.
The microstructure, physical properties, deformation mode depend on the e/a ratio which is closely related to the β-phase stability in Ti-Nb alloys.
In particular, it is very important to reduce the Young’s modulus and to control the mechanical properties in β-phase Ti-Nb alloys for the applications such as artificial joints and dental implants [1].
It is necessary to understand the β-phase stability in order to further develop β-phase Ti alloys because the β-phase stability possibly affects their physical and mechanical properties.
Conclusion It is investigated the effect of the β-phase stability on the physical properties and deformation behavior in Ti-Nb alloy single crystals.

Introduction Different methods of severe plastic deformation are currently widely used in practice to obtain metals with improved physical and mechanical properties (for example, such processes as equal channel angular pressing, extrusion, rolling and their various combinations or modifications).
Therefore, there is increasingly more need for constructing mathematical models allowing to describe as integral characteristics of material processing as material internal structure evolution, which has an influence on physical and mechanical properties.
The explicit internal variables of macrolevel model are spin of movable coordinate system Ω, effective anisotropic elastic properties П, inelastic and thermal components of the strain rate tensor.
Hardening Laws One of the key factors determining the material behavior is the change of critical shear stress for the intragranular slip systems in the process of deformation that is determined by the equation (27) in mesolevel of the two-level constitutive model (1)-(2).
The oriented hardening is considered due to the annihilation of dislocations “compressed” at the barriers, while changing the direction of deformation, as well as due to the interaction of intragranular dislocations with grain boundaries in case of polycrystal deformation, that is why the physics of the annihilation process and the factors affecting the decrease of the critical shear stress on the considered slip system as the result of the annihilation of dislocations were thoroughly investigated.
