However, background knowledge of material structure and electrical properties is required to analyze the results.
Finally, simultaneous effect of thermal and mechanical factors was studied running FSP passes in AA1100 with different overlap ratios.
These tests aimed at assessing the combined effect of mechanical and thermal factors and identify the predominance of any of these.
The electrical conductivity reproduces the shape of the nugget and its associated mechanical and thermal affected zones, as well as, the spacemen between nuggets.
The electrical conductivity clearly identifies the different zones, with marked decrease in the heat and thermo-mechanical affected zones (TMAZ) increasing in the nugget.

In this paper, we investigated the influence mechanism of four cement antifreeze components on the mechanical and durability properties of MPCC under the severe cold environment, focusing on the development law of the performance of MPCC as a rapid repair material for pavements.
Aiming at the feature of imbalance of winter constructability, mechanical properties, and durability of MPCC, this study explores the influence mechanism of antifreeze components on the performance of MPCC from the aspects of fluidity of mortar, slump of concrete, mechanical properties of concrete, and freeze-thaw durability, to seek for the most suitable antifreeze agent and dosage of MPCC for the environment of high altitude and low air temperature.

There is a growing interest in the application of ceramic as high wear resistance materials due to the unique properties.
The tribological properties of alumina and ceramic composites may be affected by their hardness, brittleness, thermal conductivity and chemical inertness [2].
One of the difficulties in examine the alumina wear data is that frequently the above mentioned test conditions factors are not described or even kept under control.
Following it will be discussed the pin-on-disc test conditions factors affecting the results of wear rate measurements and worn surface characteristics of dense alumina.
Wear properties of alumina and effect of test conditions Alumina wear behavior has been extensively studied [1-20].

Velocity Gradients and the Evolution of Material Properties in a Narrow Layer Near Surfaces of High Friction in Metal Forming Processes Sergei Alexandrov1,2 a and Yeau-Ren Jeng2,b 1A.Yu.
Plane Strain Extrusion To the best of authors’ knowledge, no systematic experimental study to establish the dependence of the thickness of the layer of intensive plastic deformation on process parameters and material properties has been reported.
It is also of great interest to relate the evolution of material properties in the aforementioned layer and in traditional processes of severe plastic deformation such as the high pressure torsion process [16].

The mechanical properties of the final product are largely determined by the state of these fibers.
The most significant factors influencing mechanical properties in compression moulding are mould temperature, pressure, and heating time.Traditionally, the majority of researchers use the traditional experimental approach, in which they alter one parameter at a time while holding other variables constant.
The selection process involves evaluating factors such as risk, accuracy, product quality, and productivity.

The properties of aluminium alloy products are affected by several factors, the most important among them being determined by the manufacturing technological process, particularly by metal forming.
During their development, the knowledge of relationships between microstructure, texture and mechanical properties has been considerably enlarged [8,9].
Static mechanical properties in both main directions are in Table 2.
During the evaluation of FCG rates, it was ascertained that the most dominant factor affecting the crack growth rates particularly in the area of smaller values and near-threshold area was the value of the coefficient asymmetry R.

Durability properties were also verified.
However, risk is associated also with the use of alternative materials, as these raw materials often exhibit divergent chemical composition, which negatively affects their mechanical, physical and chemical properties.
Next determined properties are in Tables 4 - 7.

Properties, such as thermal conductivity, dielectric constant of Si3N4-filled epoxy resin composite were evaluated, the effect of the content of Si3N4 and surface treatment of the filler was also considered.
From the theoretical view, we particularly discussed the main factors that affect the thermal conductivity of the composite.
The model of Agari's considers the effect of dispersion state by introducing the factors Cf and Cp: Log λc = A⋅Vf + B (A = Cflogλf − log(Cp⋅λm), B = log(Cp⋅λm)) (1) where Vf is the volume fraction of filler; λc, the thermal conductivity of composite; λf, the thermal conductivity of filler; λm, the thermal conductivity of matrix; Cp, the factor relating to the structure of the polymer, and Cf, the factor relating to the ease of forming conductive chains by the filler.
However, the factor Cf relates to the ease of forming conductive chains of the filler alters greatly.
The main factors that affect the thermal conductivity are incorporated in this model.
