This was to ensure the fracture toughness of the weld was measured, with minimal affect of the surrounding base metal properties.
For each heat treatment condition, microhardness traverses were performed across the mid thickness joint to determine the affect of heat treat temperature on hardness properties, which can provide insight into the resulting mechanical properties of the joints.

The main properties of the part surface layer able to affect the part service properties are the surface roughness, the hardness and the state of the residual stresses.
Over the years, the researches was directed inclusively in the field of service properties of the metallic parts surfaces previously affected by vibratory ball burnishing processes.
Patel and Kumani considered in 2011 that there many factors able to affect the results of the vibratory ball burnishing process [3].
The main factors able to affect the results of the vibrorolling process are the mechanical properties of the workpiece material, the properties of the vibrorolling tool material and the dimensions of the active zone of the vibrorolling tool, the presence and the properties of an eventual processing liquid, the characteristics of the motions specific to the vibrorolling process, the force exerted by the vibrorolling tool against the workpiece surface layer etc.
Thus, the ball vibrorolling could be applied to improve the service properties of the cylindrical parts made of steels able to be affected by the results of the ball vibrorolling process.

However, material defects can reduce physical and mechanical properties, such as hot tearing defects [4,5].
Differences in metal properties will affect to the HAZ area (heat affected zone), TMAZ (thermomechanically affected zone), and WM (weld metal) regions [11].
The variation of shoulder rotation in the FSW process is one of the determining factors for improving weld quality.
This study conducted a numerical study of mechanical properties (hardness and tensile strength).
Based on Figure 11(a) to Figure 11(b), the tensile strength of FSW weld metal has a significant decrease in the mechanical properties compared to the base metal mechanical properties.

The normal production is severely affected. 2) Sealing effect is not satisfactory.
The product’s quality is severely affected or the production is forced to interrupt.
Heat convection coefficient is the main factor impacting the distribution of seal rings temperature.
Table 2 shows their mechanical property [5].

Abstract: The purpose of this paper is to study some of the factors that affect the shear strength of Single Lap Joints (SLJ).
In the design of the adhesive joints for engineering structures, strength, stiffness and life are considered to be the most important mechanical properties.
While some adhesives can be used up to 260ºC, elevated temperatures are usually a cause for concern; (c) High-strength adhesives are often brittle (poor impact properties).
The purpose of this work is to present a study about the influence of several factors of the bonded joints process in its shear resistance, focusing on temperature effect in mechanical resistance.
Material and Methods Specimen geometry and material properties The SLJs were manufactured with an epoxy resin combined with ceramic particles adhesive (ARC 858).

The particle shape is also a principal factor in influencing flexural strength.
This, however, not only increases the final cost of the material due to the high cost of the filler, but also often impairs the mechanical properties of the material.
The conductivity of composite is affected by various factors such as the volume fraction, shape and size of the conductive filler [4, 6].
The embedding of G platelets in Cu dendritic arms as displayed in the SEM micrographs suggests an improvement of mechanical property.

The properties and characteristics of the circuits are different in accordance of the flow valve we use.
The volume efficiency and physical dimensional deviation of the system are the primary factors that affect the synchronization precision.
Although the closed loop control hydraulic synchronous circuit has a complex composition and costs more, it can overcome the disturbance from all kinds of factors that will influence the synchronous accuracy and obtain a high precision synchronous drive control.
Factors Affected the Synchronous Precision Variation in Load.

Improvement of mechanical properties in Al alloys can be achieved by precipitate strengthening.
For other types of Al alloys, significant improvement of mechanical properties may result primarily from grain size refinement.
In the recent work [9], the influence of hydrostatic extrusion on the mechanical properties of 6082 aluminium alloy has been reported.
The shape factors of 'black' inclusions remain almost constant (Fig. 8a).
For the inclusions containing Si and Mg, both shape factors remain independent of the size.

The tensile properties of TRIP steel at room temperature were also measured.
In addition, the properties of TRIP steel were markedly decreased because martensite, which was deleterious to the ductility, was present in microstructure of the steel soaking at bainitic temperature 350for 6 mins.
In present work, Gleeble3500 thermal simulation testing machine, Nikon330 optical microscopy, X-350A X-ray stress instrument and CMT5305 electronic universal testing machine are used to study the effect of heat treatment on microstructure and mechanical properties of TRIP steel containing aluminium.
Yield strength was mainly affected by bainite with higher strength and hardness.
The properties of TRIP steel were markedly decreased because martensite, which was deleterious to the ductility, was present in microstructure of the steel soaking at bainitic temperature 350.

● Cation substitutions, structures and properties change, forming new minerals.
