Effect of Anisotropy on the Thermoelectric Properties of Bi1Sb3Te6
Added with Au Alloys Prepared by Mechanical Alloying Process
W.K.
An effect of anisotropy on the thermoelectric properties of Bi1Sb3Te6 added with Au alloys prepared by a mechanical alloying process has been studied.
A highly anisotropic hexagonal crystal structure which has weak van der walls bonding along the c-axis is the reason of low mechanical properties; especially the brittleness caused by cleavage fracture.
The change of (1 1 0) plane which is perpendicular to the basal plane appears to affect the thermoelectric properties.
Results and discussion The effect of anisotropy on the thermoelectric properties of Bi1Sb3Te6 added with Au alloys prepared by a mechanical alloying process has been studied.

Since no antibacterial properties of bacterial cellulose alone as a packaging material, there is a non-antibacterial properties of defects.
From product performance point of view, the current foreign biodegradable antibacterial plastic mechanical properties and biodegradation properties and antibacterial performance, these plastics are biodegradable antibacterial play an important role.
Test methods Orthogonal Design.The inhibitory effect of biodegradable cellulose packaging material mechanical properties of many factors, the experimental analysis of the information obtained, directly affect the test results, there are three underlying causes can be made of polystyrene dosage, microcrystalline cellulose usage and the amount of titanium dioxide.
In the case of normal temperature and pressure molding time was 12h, emphasis on the amount can be made of polystyrene, microcrystalline cellulose, and the amount of toluene and acetone delivery compared to the physical and mechanical properties of materials, so the experimental design three factors, three levels L9 (33) orthogonal test table.
Antibacterial properties also reflect the best.

Physical properties of sands and the recycled waste.
On the contrary, the factors DS content and RA content, as well as the interaction between the factors DS content and BW content (DS×BW), do not significantly affect the flexural strength of the eco-mortar [41].
On the other hand, the ANOVA analysis shows that the DS content and RA content factors do not significantly affect the two tests.

Abstract.
Converter body is the core device in oxygen converter, the thermal-stress is the major factor affecting the lifetime of the converter, ansys the stress level in different parts of the converter is essential to improve the converter life.
The thermal-stress BOF shell suffered when working is the main factors affecting the life of the furnace shell, the main factors affect the BOF shell stress level is static load, dynamic load and heat load, heat load in a dominant position in BOF total stress component.
Pure Penalty: (2) Augmented Lagrange: (3) Because of the existence of an additional factor, Augmented Lagrange becomes insensitive to Pure Penalty.
In front of carrying thermal-stress analysis, material properties in different part need to be defined, the involved physical include thermal expansivity, elasticity and poisson ratio of shell material, permanent layer and working layer refractory material, they can be determined by literature[2,3].

This publication includes factors which affect the mechanical properties of PM titanium along with an overview of the developments in advance particulate processes over the last decade.
Factors Effecting Fracture Toughness of Titanium and Titanium Alloys The fracture toughness of titanium and titanium alloys can be affected by many factors such as interstitial element content, microstructure, heat treatment and other factors such as porosity which is particularly associated with PM produced titanium and its alloys.
These act as defects in the material and adversely affect the mechanical properties.
Other Factors One of the major concerns associated with a conventional pressing and sintering PM technique is residual porosity which can significantly influence mechanical properties of the resulting compact.
· It is clear that the level of interstitial impurities affects the mechanical properties of IM titanium and titanium alloys.
