According to the review of the publications mentioned in the Introduction, factors such as the synthesis conditions, the volume percentage of ZrO2 -Si3N4, the orientation and geometry of the ceramics within the matrix, and other variables all impact the mechanical properties of the composites[17].
The presence of ZrO₂ influences the sintering behavior by stabilizing certain phases and improving toughness [31], affecting mechanical characteristics.
Other contributing factors to the strengthened mechanical characteristics include a decrease in crystallite size and an increase in lattice strain caused by including refractory particles [38].

These excellent mechanical properties may be caused by the finely dispersed retained austenite and refined bainitic ferrite and/or martensite brock by thermomechanical rolling process.
In general, thermomechanical treatment is effective for improving the mechanical properties and microstructure of steels.

In recent years, there has been an interest in the
development of TiAl intermetallics because of their unique properties such as low density, good
stiffness, high elevated-temperature strength, and excellent oxidation resistance.
All the materials were assumed as uniform and isotropy in this work, and the materials properties used in this calculation are listed in Ref. [9].
The effects of temperature change on the materials properties (elastic modulus, thermal expansion coefficient, poisson ratio, work hardening and yielding strength) were taken into accounted.
From this we deem that the most important factor affecting performance of joint is the distribution characterization of residual stress in the minute area adjacent to bond-line of the base material with smaller coefficient of thermal expansion and interface brittleness phase, so the distribution of stresses in this area should be concerned on when analyzing the residual stresses of joints.
Literatures show that the most important factors affecting distribution characterization of residual stresses are mechanical and physical performance of materials, namely, α, E, σ0.2, and w. α is thermal expansion coefficient of materials, it is the most important factor to bring residual stresses of joint in diffusion bonding of dissimilar materials.

Addition of antimicrobial substances such as silver or titanium nanoparticles has been shown to enhance the antimicrobial properties of PMMA resin by reducing microbial adhesion [3-5], but in turn may affect the mechanical and physical properties of the material [6].
It should be kept in mind though, that with the improvement in antimicrobial properties of the material, the physical and mechanical properties should also be maintained within ISO standards.
Therefore, the addition of vanillin can also affect the properties of the original material.
The flexural properties of PMMA resin can be affected by various factors such as cross-linking agents [19], residual monomers [20], powder to liquid ratio [21], porosity [22], curing process [23], and water sorption [24].
The incorporation of vanillin into self-curing orthodontic PMMA resin can affect its physical properties, namely flexural strength and flexural modulus.

These observations may be due to difficulties of mortar matrix mixing at initial fibre inclusion, which can promotes air entrapped and fibre balling, thus affecting the composite mechanical resistance.
The results revealed that notwithstanding the bridge role of fibres in the matrix, the problems associated to compacting of the cement matrix at initial fibre inclusion, can promotes air entrapped, thus affecting the composite mechanical resistance.
Work is in progress to allow the understanding of the cracking mechanism by evaluating the fracture surface and stress-strain profiles, as well as other FRC properties that can affect their mechanical resistance, such as porosity, shape and diameter/length fibre ratio.

The effect of hot forging reduction ratios (1.11 and 1.29) on the hardness and mechanical properties are studied.
Good mechanical properties can be obtained by a combination of plastic deformation and thermal treatment.
Heat treatment is one of the major factors used to enhance the mechanical properties of low alloy steel.
An aging treatment before warm working is essential to the development of better mechanical properties.
Optimum mechanical properties can be obtained when heat treatment is carried out following TMT. 6.

During pressing using high speed, the material is stressed to the limit of its mechanical properties.
For this reason, opens debate on the factors previously neglected, such as the strain rate.
If the material is stressed dynamically, an important role is played by factors that can be neglected in quasi-static loads.
These factors include the strain rate, temperature, final degree of deformation, the effect of inertial forces, structural changes or the range of tension forces [1].
Despite the main purpose of this experimental equipment, i.e. monitoring the response of the material on the applied strain rate, this device can also be used to monitor other factors affecting the forming processes.

The mechanical heterogeneity has been estimated by the micro hardness test.
The data for crack size in weld and heat affected zone was obtain from microscopic observation, and for mechanical properties from microhardness testing.
So for velocity of crack the dimension factor used was equal to 100.
The mechanical heterogeneity could be estimated by micro hardness test.
One of the good methods of nondestructive testing could be microhardness control of the weld and heat affected zone to avoid the significant modification of mechanical properties of welded structures.
