The recent development in thermo-mechanical modelling of FSW process is described with particular reference to two major factors that influence the performance of FSW joints: material flow and temperature distribution.
Consequently, the properties of FSW have been the subject of a considerable amount of experimental and numerical studies [4-10].
Temperature dependent properties of the weld-material have been used for the numerical modelling.
The results also indicated that weld speed could be the main input parameter that had the highest statistical influence on mechanical properties.

This factor can significantly affect the performance of both the tool and the bearing units of milling machines, as well as the processing quality of the workpiece.
It should be noted that it is important to have a set of high level band-pass filters to identify the vibrations levels arising at the tooth frequencies and multiples thereof frequencies which characterize the defects, cutter wear process, affecting durability and processing quality of the equipment.
The choice of this material is based on its widespread application due to good machinability and good mechanical properties.
For vibrodiagnostics of the milling machine, it was decided to carry out an experiment with three varying factors (cutting width ae=const): rotational velocity n; cutting depth ap; feed s (Table 2).

Selective Laser Melting can form metal parts with fine grain size, uniform structure, density of almost 100%, excellent mechanical properties and other characteristics [3].
Analysis of Surface Hardness Studies have shown that selective laser melting properties were connected with the grain particle size, grain arrangement, the degree of organization and uniformity defects in the form of other factors.
The surface hardness of the sample with the linear energy increases firstly and then decreased to increase overall, this is because the linear energy level determines the degree of melting metal powder, thereby affecting the properties of the sample.
Metal powder characteristics, shielding gas, oxygen content and other factors affect pores production.

There are many factors to be examined about the impact of bond properties, such as diameter, bond length, concrete strength and temperature, etc.
Although some scholars have already studied the above aspects, however, due to many influence factors and the great difference, there are differences in the test results.

Meanwhile similar material matching program with 5 factors and 6 levels was designed by using Uniform Design Method.
And the physical and mechanical properties of the similar material compressive strength was measured under different proportions circumstances.
According to the requirement of the similar material, choose the basis of similar material: (1) The main mechanical properties of model is similar to simulative coal body, (2) In the process of experiment material mechanical performance is stable, not easily affected by environmental conditions, (3) Change the ratio of material to adjust some properties of the material to adapt the requirements for similar conditions, (4) Manufacture is convenient, solidification time is short, (5) The cost is low, abundant sources.

In recent years, there have been considerable interests in their medium-range order (MRO) structures, which surely affect the glass forming ability as well as mechanical properties.
The quantitative relationship of such a MRO to the glass forming ability and to the mechanical properties is currently major concerns.
Since the large internal displacements, which are intrisically involved in the stress-strain response, generally arises in the inhomogenenuos amorphous strucutres, it may be much affected to the elastic properties.
Thus, inter-penetrating icosahedral cluster is one of the possible factors to explain the 5% difference observed in Fig. 3.
It is reasonable to suppose that such clusters also can be causal factors contributing to the correlation between the global elastic moduli and the free volume content.

Investigation of Mechanical Properties in Ductile Iron with Alloyed and Unalloyed at Time and Temperature on Austempering T.
The progress of spheroidal graphite iron's properties was significantly influenced by the pace of cooling and the extinguishing process.
These factors make it necessary to continually create new materials and consider everything.
