At the same time, research directions №2 and №4 are actual since they are aimed at wastelessness of engineering and metallurgical enterprises, but for welding of critical structures these welding materials are allowed only in rare cases.
Thus, welding fused flux compounds manufactured by granulation with electric arc of favorable spherical shape has homogenous chemical composition, it is not hygroscopic with strong granules.
In addition, if carbides or ferro-alloys of metals are added to the rock furnace burden, it is possible to dope granules thus to produce doped fused welding flux, but it requires inert atmosphere and further investigation.

Introduction Metal oxides are a large class of compounds [1-3].
There are two types of RMnO3 compounds.
In particular, the nonlinear elasticity of transitions metal compounds such as TiB2 [22], MgO [23] and MgSiO3 [24] and have recently shown the success of this approach.

If no chemical compounds containing A4 are formed on the surfaces which are in contact with the liquid metal, then the values of D1(2) and D2(1) will not depend on x4.
The formation of compounds of this type occurs when the oxygen concentration in Na reaches the so-called threshold concentration for the formation of a complex oxide.
For each compound at a given temperature, there is a strictly defined value for this parameter.

This problem is not unique to aluminum alloys or aircraft however.
It is based on the aluminum alloy 7010-T7651 used in the RAAF Hawk.
Corrosion Inhibiting Compounds have been shown to be effective in achieving this [6].
Summary This paper has described models which predict how corrosion damage affects the fatigue life and failure locations of fatigue specimens of the aluminum alloys 7010-T7651 and 7050-T7451.

As an additional reference a graphite-free lubricant was considered which is recommended for the warm forming of steel, special alloys and nonferrous metals to obtain lubricant free products.
Using modified plasma conditions (lower ratio pd:pp) it was possible to define a type III process without compound layer and similar nhd but higher surface hardness.
A further investigation of the development of the tool topography of forging dies during processing and according wear mechanisms is the global aim of the project “TopoSchmieden”.
Aim of the work is finding localized treatments for complex industrial dies.
