Moreover, in these alloys, we observed a long-range ordering, which can significantly affect the mechanical and physical properties and their stability.
It should be emphasized that formation of properties of Fe-Al alloys in heat treatment and plastic working processes is under strong influence of long-range ordering and so-called vacancy hardening occurring in these alloys.
George and Baker [9] point out that explanation of mechanical properties of Fe-Al alloys is based on a balance between two phenomena: firstly, the presence of thermal vacancies, which cause hardening of the material, and, secondly, thermal vacancies causing dislocation creep (glide and climb).
The factors influencing the vacancy elimination (softening effect) were analyzed.
The authors of [11] point that, irrespective of the chemical composition, two factors have an important influence on the softening rate of the alloys: rate of vacancy migration determined by the value of effective enthalpy of vacancy migration, and density of sinks for vacancies.

Platinum matrix composite is a new type of functional pottery material, which has excellent mechanical, electrical and optical properties.
For the Platinum matrix composite materials, the performance of the Pt-C compounds will be influenced by many induced factors, such as the electrical properties, mechanical properties and thermal properties, so the synthesis method of the Pt-C compounds will help other researchers a lot.

In this paper, the XLPE/PVC cable running for 17 years was investigated by using thermal analysis, microstructure analysis, mechanical property analysis and dielectric properties analysis.
In the long-term running process, the physical and chemical properties of XLPE would have some change under the effect of heat [2-4], and these changes would affect the safety operation of the cable [5].
Mechanical properties Figure 6 is a comparison of the mechanical properties.
According to figure 5, the size of spherulites in the inner layer is larger and the arrangement of spherulites is not regular, it led to its poor mechanical properties, meanwhile, the temperature of inner layer is higher, some XLPE macromolecular chains may be break during long term operation, therefore, its mechanical properties became poor.

Ni-based superalloy single-crystal turbine blades are widely used in gas turbines for aircraft propulsion and power generation as they can be subjected to high service temperature and show high mechanical properties due to the almost total elimination of grain boundaries.
It is of fundamental importance analyzing the physical mechanisms of formation of stray grains, to understand which thermo-physical and geometrical factors highly influence their formation and to find possible ways to reduce the impact of the problem.
The study allows to derive the preferred locations of stray grains formation and the role played by the most affecting factors: (i) geometrical: angle of primary grain dendrites with withdrawal direction and orientation of the primary grain with respect to the side walls, responsible for the formation of volumes where the stray grain undercooling is lower than the undercooling of the columnar dendrite tip; (ii) process and alloy: thermal gradient ahead to the solidification front and alloy composition, influencing the columnar dendrite tip undercooling; (iii) wettability of foreign substrates, on which the stray grain undercooling strongly depends.
Because of the adverse effects of high angle grain boundaries on mechanical properties, the presence of these unacceptable defects in single crystal components causes a significant decrease in the mechanical properties of the component.
A relevant factor is the β angle between the wall and the local tangent to the liquidus isotherm.
