Plastic deformation at high temperatures affects these phase transformations, but also low-temperature deformation leads to different properties of the resulting microstructure, and can be influenced by recrystallisation annealing.
Multiphase steels The different phases that have been discussed in section 2 are in general very diverse in their mechanical properties: ferrite is not strong, but very ductile, martensite is extremely strong and brittle, pearlite and bainite have intermediate properties, which strongly depend on the internal carbide distribution.
It is clear that a wide range of (mechanical) properties can be obtained for multiphase microstructures, but the relation between the microstructure and the properties is not straightforward for complex multiphase microstructures.
It is known that martensite can contain carbon concentrations between approximately 0.3 wt.% and over 1 wt.%, which is a condition that is to be taken into account when considering the mechanical properties.

The factors on the effectiveness of surfactants were also discussed which include surfactant kind, diamond concentration, bond composition, diamond mesh, circumstance temperature and properties of stone.
Some kinds of coolant with good properties were developed such as metal cutting coolant.
The effectiveness of coolant in diamond blade sawing is affected mainly by the surfactant, diamond concentration, composition of bond and the properties of the stone. 198 Machining of Natural Stone Materials Surfactant Kind.
The effectiveness of coolant on segment wear is related to the properties of the segment bond, as shown in Fig.2.

These regions may have less advantageous mechanical properties; nevertheless they can serve as lubricant in the wearing process.
Experimental results Due to the numerous factors influencing the behaviour of the tribological system the evaluation of tribological test data supposes a very careful treatment.
SiC, complex oxides, etc.) are assumed to be created during heat treatment that caused significantly different properties (HV, E) in closely neighbouring areas of the specimens.

The binary ART method uses the property of x-ray absorb rate of metal, silicon and other non- metal material are extremely different.
The relaxation factor can improve quality of reconstructed image by using the ART under noisy condition.
The suggestion of the magnitude of the factor is between zero and two.
This affects the image quality a lot, and makes the image blur.
However, the real detector properties still need more study for more accurate analysis.

However, in selecting a suitable wear testing machine, the following criteria should be considered; the properties of material of the component being tested, contact between the components, and whether the test machine’s environment is similar to the actual working environment [7].
The reason that the weight loss had no significant difference was because the wear mechanisms of wear that occur with hooks from both the testing machine and the weaving machine with the same mechanism (Fig. 4) and level of factors that affect wear rate were similar [10].
When it came in contact with yarn, small scraps of coating would wear off of its surface but this did not significantly affect the hook’s weight loss.

Coarse and fine aggregate retrieved in such a way is very similar to original one in terms of its physical and mechanical properties.
Heterogeneity has been significantly reduced by : · elimination of coarse aggregate (replaced by sand of maximum 600µm), · enhancement of mechanical properties of concrete stone, · decrease of aggregate amount in relation to the suspension [4,5].
The study refutes the hypothesis of the lack of significant influence of any of the factors on the body density after 28 days.

Methods for describing complex materials, as well as the nature, characteristics, and changes of the material after being affected by the environment, especially the influence of the structure of the material on the macroscopic properties of the material.
The object examined by classical elastoplastic theory is homogeneous, continuous, and infinitely separable materials, that is, materials that maintain their original characteristics and properties no matter what scale they are.
Due to their structure, the characteristics, characteristics, or properties of materials are complicated.
The microscopic and mesoporous characteristics of the rock and soil porous medium strongly affect its macroscopic characteristics.
For example, its macroscopic properties such as impermeability, durability, strength, and deformation properties are closely related to the microscopic and mesoporous characteristics.

These factors may lead to different types of corrosions and erosion and therefore, an investigation regarding the effect of these factors should be addressed and considered.
Coarse rather than fine grains were more affected by the corrosion attacks.
Nevertheless, the solution seemed to have a great influence on the properties of corrosion products and transport activities of aggressive chloride ions and oxygen.
These factors were found to have a significant effect on the corrosion rate of copper pipes in both stagnation and flowing conditions.

Products of nominally the same form, but manufactured through different routes, could have markedly different properties.
This not only affects mechanical considerations such as stiffness and strength, but also other attributes such as surface finish, chemical resistivity and internal damping.
The mechanical properties are not strongly dependent on composition, but chemical behaviour which is reflected in terms of durability and strength retention in corrosive environments is influenced by chemistry.
However, the selection of the production and design of fibre to use in a particular application will depend on many factors, including the type of structure, the expected loading, and the environmental conditions.
When taken together these two properties lead to fibre composites having a strength–weight ratio significantly higher than steel plate in some cases.
