One of them is by reducing long-range ordering or grain size of intermetallic compounds [1, 2].
Nowadays, mechanical activation has come to the fore in fields such as the production of intermetallic compounds [4, 5], supersaturated solid solutions [6], amorphous materials and metal matrix composites.

The paper present some general aspects regarding results obtained by ISIM Timișoara at FSW of steel alloys, with wide use in important industrial fields.
Experimental Program The experimental programs for the FSW steels were carried out at ISIM Timișoara, ensuring more severe technical and technological conditions, compared to those from the welding of light alloys (except for titanium alloys)
It has been shown that, when applying the FSW process to welding S 420MC steel, granulation refining in the nugget is obtained, similar to aluminum alloys.
Under the shoulder of the welding tool and under its action, a darker area (A) was formed in which it is possible to have formed intermetallic compounds or other formed compounds, due to excessive wear of the tool during the action of the tool on the base metals.

However, there are opportunities for analyzing the mechanical performance of such method in SLJ with materials of different properties, such as ductile structural aluminum alloys and high strength steels.
In the same way, aluminum alloys (Al alloy) are also facing an ascendant usage at these industries, because of the lightweight associated to good mechanical and corrosion resistance properties [2].
The most used welding method for sheet metals is the resistance spot welding, which is not suitable to join Al alloys to steel because of the fusion and solidification of parts.
The low solubility of Fe in Al can leads the formation of brittle intermetallic compounds, such as FeAl3 (θ-phase), Fe2Al5 (η-phase) and FeAl2 (ξ-phase) [3].

Experimental Detail Melting of Samarium cobalt alloys was carried out in induction melting furnace.
Two alloys were made.
First alloy contained 65 percent cobalt and the second alloy contained 40 percent cobalt.
Powder of both alloys was prepared by crushing and grinding under inert argon atmosphere.
Samples with varying proportions of two alloys were prepared and pressed isostaically in rubber molds at a pressure of 300 MPa.
