This study was carried out to investigate the effects of grain size on mechanical properties in Cu-Sn foil with a thickness of 30 um.
Mechanical properties were found to be strongly affected by microstructural features including grain size.
It is well known that mechanical properties of metals are strongly influenced by grain size.
Fig.5 Tensile properties as a function of annealing time In thin films, grain size as well as film thickness has been considered as important factors that can affect tensile properties.
However, the mechanical properties obtained from the present study are not explained by this theory.

The mechanical properties of the AZ31B alloy sheets processed by differential speed
rolling (DSR) from the cast ingots homogenized at two different conditions were investigated.
However, there are few studies on the effects of homogenization of the cast ingot on the microstructure and the mechanical properties of the subsequently hot-rolled magnesium alloys, and the optimum homogenization condition is still unclear.
The DSR processing is a potential technique for enhancing the mechanical properties and the formability of the magnesium alloys [9,10], but it is more sensitive to the hot workability compare with the normal symmetric rolling because of the severe shear deformation.
In this study, a DSR processing was carried out on the AZ31B alloy cast ingots homogenized at different conditions in order to investigate the effects of homogenization on the mechanical properties of the hot-rolled sheets.
Therefore, the differences in the mechanical properties of the DSR processed sheet can be considered mainly due to the distribution of the Al and Zn in the matrix in the present work.

Various researchers [20, 22-23] have revealed conductivity variation according to different factors: CNT amount, temperature, and velocity of the injection/extrusion, strain, etc.
The purpose of this study is to investigate the influence of multi-wall carbon nanotube (MWCNT) content, injection molding temperature and annealing time on the mechanical and electrical properties of the multi-wall carbon nanotube-reinforced thermoplastic polyurethane (TPU/MWCNT) nanocomposites and to determine the most important factors that affect their properties.

Moreover, with the increasing demand for materials with good performance, it becomes pertinent to develop ways that will counter these drawbacks without affecting the entire characteristics of the substrate.
One of the essential factors in laser surface cladding is the powder particle size.
The uniform distribution of SiC particles in the Al-Sn matrix had a good effect on its mechanical properties.
Mechanical Properties of Al-Sn-SiC Composite Coatings Research had been made to estimate the mechanical properties of materials from bulk hardness measurement ever since indentation testing has come into existence, especially yield and tensile strengths [27].

MECHANICAL PROPERTIES OF AN AMORPHOUS OR PARTIALLY CRYSTALLIZED
ZIRCONIUM BASED METALLIC GLASS
J.M.
Viscoelastic properties are studied by mechanical spectroscopy in large frequency and temperature ranges, both below or above the glass transition temperature (Tg), whereas viscoplastic properties are investigated by compression tests .
To study the interaction between crystallization and mechanical properties at high temperature, nanocomposites are produced thanks to appropriate heat treatments.
The aim of the present work is to compare the mechanical properties of the amorphous Vit 1 with a sample that was previously annealed leading to partial crystallization.
The viscoelastic properties are analyzed thanks to the quasi-point defects theory [10, 11] and their variation with crystallization are compared to the variation of viscoplastic properties deduced from compression tests. 2.

Among them, the inorganic fillers play an important role in the mechanical properties[2,3].
Some of the factors influenced the cured depth of composite resins.
The ratio of inorganic filler and cured depth also affect the mechanical properties of composite material.
The former plays an important role in mechanical and chemical properties.

The selection of biomaterials and the design of the scaffold is crucial, as it directly influences the mechanical properties, which in turn affect cell behavior and tissue integration.
Tensile tests were performed to measure mechanical properties, including Young’s Modulus (E), Poisson’s ratio (ν), and porosity—properties critical for understanding the interaction of scaffolds with cells and tissues.
Although the two auxetic structures shared the same undulation angle, the analysis revealed differences in their mechanical properties.
The latter was found to have a significant influence on the functional behaviour of the scaffold [42], affecting the interaction between cells and the structure [43].
Results and Discussion Mechanical Properties The tensile tests were analysed to obtain Young’s Modulus for each geometry.

The mechanical properties and microstructure of zirconia-toughened-alumina ceramic composite doped with nano particle of MgO is investigated.
A number of properties of Al2O3 are closely related to atomic and electronic structures of intrinsic point defect and dopants.
Besides ZTA, magnesium oxide (MgO) has an important effect on mechanical and electrical properties of bulk Al2O3 [5].
Properties such as density and Vickers hardness were measured.
Factors like micro-structural features and densities are important properties that significantly influence the hardness of ZTA–MgO composite.
