The mechanical properties of various nanowires are tested by tensile process to determine their elastic module and yield stress versus radius size.
The mechanical properties of materials also change with its scale as the system size reaches to nanometers.
The loading rate and temperature are also the central factors to influence the mechanical properties of nanowires.
Although much work has been dedicated to the study of size effects on the mechanical properties of metallic nanowires, we still want to know some basic knowledge on the structural stability and mechanical parameter of various wires under different orientation systematically.
Conclusion In this paper, MD simulation is performed to predict the structural stability and mechanical properties of Ni nanowires.

Mechanical properties are very important, because determination of these properties is necessary for structural analysis and reliability evaluation of the electronic packages.
Measurement of the Young's modulus is complicated by several factors such as the limited region of elastic behavior, microstructure of material, variations in cooling rate, micro porosity in the solder, and so on.
To examine effects of microstructure on mechanical properties, cooling rates had been controlled to acquire different microstructures of solder materials.
Young's modulus of solder materials were measured by nanoindentation tests and other elastic properties had been acquired by mechanical tensile tests.
As the cooling rate decreases, Sn-rich phase grows and elastic properties approach to the properties of pure Sn.

Introduction Austenitic stainless steel is well known as excellent engineering material due to its good atmospheric corrosion resistance, formability, weldability and superior mechanical properties in cryogenic temperature [1].

The effects of negative bias voltage on morphology, hardness, adhesion strength, microstructure and tribological properties were studied.
The deposited samples were characterized for its compositional, structural, mechanical, and tribological properties.
Tribological properties Friction coefficient curve of films at different bias is showed in Fig.9.
Affected by different bias voltages, wear ratio of composite films decreased as the bond strength increasing, indicating that bias voltage affected the wear weightlessness of composite films through affecting the bond strength between films and basal body.
Combined the analysis of the influences of bias voltage on the surface morphologies and phase structure, surface morphologies and wear-resistant properties of films keep approximately same change tendency, indicating that the wear-resistant properties of films were affected by bond strength and surface morphologies together.

The general rules of various factors impacting on burr formation were obtained in micro-machining process.
Metal cutting burr is formed in the cutting process and all factors that affect the metal cutting process will affect the formation of the burr.
The shape and size of the burr in cutting process not only depend on the combined effect of various factors but also organizational status and mechanical properties of the material, the tool geometry, cutting capacity, machining methods and the support stiffness in terminal ministry of the workpiece and other factors [2].
Therefore, the research on formation mechanism and influencing factors of the micro-burr will help improve the quality of micro-parts.

The results show that coating affects greatly the stress distribution near the hole edge, and the stress concentration factor in the coating increases with the coating thickness but decreases in the plate, and it increases with the shear modular ratio of the coating to the plate but decreases in the plate.
But their thermal expansion factor, elastic modulus and other properties do not match with each other.
The results [4] show that the drilling process will produce the ringed work-hardening layer near the hole edge, whose properties are changed greatly.
The above results indicate that the stress concentration is little affected by the coating, but greatly affected by the coating material shear modulus.
