Copper alloys provide exceptional thermal conductivity, commendable mechanical qualities, and notable durability throughout a wide range of temperatures.
According to the author, the rupture behavior of copper and aluminum alloys can be seen as exemplifying the two distinct extremes of stress sensitivity in rupture.
The behavior of other alloys that are resistant to creep is within a spectrum between the two aforementioned extremes.
Other compounds present in significant quantity are Ferric oxide (3.85 %) and Lead oxide (3.03 %) while Molybdenum oxide, Chromium Oxide, Zinc oxide, Manganese oxide, Aluminum Oxide, Silicon oxide and Cobalt oxide constituent range from 0.94 % to 1.82 % with combined weight percentage of 1.4 %.

Since the materials of construction are required in addition to the mechanical properties of high heat resistance, thermal shock resistance, high corrosion resistance composite aggressive atmospheres containing compounds such as oxygen, sulfur, chlorine, water vapor.
The construction materials must have good mechanical properties in addition to the high heat resistance, thermal shock resistance, high temperature corrosion resistance in a complex, aggressive atmospheres containing compounds such as oxygen, sulfur, chlorine, steam [1,5-11].
The aim of this paper is to present the selected research of oxidation resistance of multiphases coatings, sprayed by innovative methods.

AM started with using plastics because of ease of processability and aim of making just visual prototypes.
Processing leads to the formation of small grains, non-equilibrium phases and new chemical compounds depending upon the composition of the powders resulting into mechanical properties (yield strength, ultimate tensile strength, ductility) better than corresponding wrought products.
LENS uses mainly iron-, titanium- and nickel-based alloys.
SLM, LENS and EBM are not inexpensive for easy-to-machine materials i.e. aluminium and magnesium alloys.

While the pure metal has failed to meet the developing requirements, it will be one of the tendencies of the development of the materials science to compound material.
With the aim, when the strength of magnetic field rises and falls, it will how to influence the distribution of the Al3Zr+ZrB2 particles in the (Al3Zr+ZrB2)p/2124 composite material and wear performance in the room temperature.
In the same load, with the increase of the magnetic field strength, 5 kinds of the wear amount of pure matrix alloy and the composite material preparation in different magnetic field stirring conditions is in turn decreasing.
Al3Zr+ZrB2 particles' strengthening function for 2124 alloy makes the strength and wear performance of composite material be obviously higher than the 2124 base alloy, and with size and distribution Al3Zr+ZrB2 particle uniform and fine, the strengthening function for composite material will be more obvious

Ti alloys are preferred choice for dental implants as compared to pure Ti.
Annealed Ti-7 wt.% Mn alloys (higher mechanical strength than pure Ti) showed a stabilized corrosion resistance compared to the other alloys as concluded from OCP data which is confirmed by the EIS. 2.

These techniques had been used to produce composite powders such as 316LTaC, 316L-NbC and oxide dispersion based super-alloys.
The mechanisms involved in the formation of a broad range of alloys depend on plastic deformations, and hence defects accumulated upon milling.

Introduction Magnesium alloys have greatly gained stake in application fields of the automobile and aeronautical industry.
Lightweight engineering has made magnesium alloys very sought-after.
Magnesium alloys and steel for example react to varying strain rates in a way, that high strain rates lead to higher yield stresses and vice versa [5–7].
These affect the deformation behaviour strongly during hot forming of magnesium alloys as they are activated additionally to the low temperature dominant deformation mechanisms basal slip and mechanical twinning.
