On the contact surface of AN40 alloy-nickel, on both sides, there was a visible discontinuous intermetallic phase separation Figure 24 b. In some spawalnicwo the particles of steel, which have been in the closure weld, microcracks have occurred.

The joints of aluminium and aluminium alloys with the different types of steel were studied. Finally, the issues related to the selection of optimal parameters of friction welding process were also investigated. In the dissertation [ 34 ], some examples of welding the AA aluminium alloys with SS low carbon steel were presented. In this article results of studies on cracks formation susceptibility in braze-welded joints of thin aluminum sheets and double-sided zinc galvanized steel sheets for car body parts made by laser brazing with high power diode laser ROFIN DL and CMT MIG-brazing, with filler material in form of powder and wire accordingly, were presented.
The intermetallic phases had width of 3. The surfaces of the samples for friction welding have been prepared with turning and washed in ethyl alcohol, directly before welding. Even the analysis of the aluminium-iron dual system leads to the conclusion that sufficiently long time and high temperatures of the process can cause the formation of intermetallic phases and can be the reason for brittleness of joints Figure 1. The quality of the joints has been evaluated on the base of static tensile test and microhardness measurements.
Figure 9 presents the microstructure of the bonding zone of the friction welded AlMg3 aluminium alloy-X10CrNiTi austenitic steel joint, together with a microhardness measurement. Sign in to annotate.

The paper presents our actual knowledge and experience in joining dissimilar materials with the use of friction welding method. So, for joints that have been friction welded with low friction time, there was a continuous narrow diffusion zone with a diameter of few micrometers Figure 13 a and the joints formed at longer friction time were characterized by local thickening of the diffusion layer and discontinuities on the aluminium side Figures 13 b and 13 c.
The welding schedules, electric parameters of welding, electrodes materials and electrodes life time by resistance spot welding aluminium were described. Such behaviour may be caused that despite forming the intermetallic phases on the bound of AlMg3 alloy-X10CrNiTi steel, the low thickness of the whole additional interlayer allowed stress transfer occurring in the joint during bending.

But the alloying additions, which are present in aluminium alloys especially magnesiumusually aggravate the metallurgic conditions of aluminium bonding.
On the edges, this layer has occurred in minor amounts, while in the middle of the joint it did not occur at all, which was related to the lowest rotational speed in this area.
There is also a possibility to bond aluminium and steel or aluminium alloys, with the friction stir welding method FSW [ 3233 ]. The view of the joint after the friction welding is presented in Ambroziwk 23 aand the view of the joint after removal of the flash with a visible interlayer from nickel can be seen in Figure 23 b.
The technological bending test has proved the strong deformation at the aluminium layer. View of friction welded joints of View at Scopus T. Abstract The paper presents our actual knowledge and experience in joining dissimilar materials with the use of friction welding method. The different research issues that can occur during friction welding of dissimilar materials were described in this paper.
Strength properties of the steel-aluminium joint, welded at various parameters according to [ 17 ]. Further researches have been concerned with a proper preparing of the nickel surface.
Until now, it has not been possible to obtain any welded joints of chromium-nickel austenitic steel with AlMg3 aluminium alloy, with sufficient plastic properties for direct joining.
Comparing the shearing work and the calculated surface area of the aluminium deposition on steel after the shearing test has allowed to observe the dependence for increasing the shearing, together with increasing the surface covered with aluminium Figure The microstructure in the bonding zone of the friction welded AlMg3 aluminium alloy-X10CrNiTi austenitic steel, together with a measurement of microhardness a and a bending test b.
In the Al-Fe equilibrium system, there is no solubility in a solid phase. The results of the investigations on the microhardness of such joints are shown in Figure The friction welded AlMgSi0. Therefore, the measurements of the shearing work, carried out for various stages of the test, have shown that there were huge shearing work differences for the analysed joints, and they have depended on the process parameters.
The analysis, of the dual systems from aluminium, has allowed the assumption that none of metals have not formed concentration of the solid solution without intermetallic phases in the whole range. The aluminium alloys with magnesium, especially the AlMg3 alloy, are commonly used in industries, where the higher strength properties comparing to aluminium are necessary. Since the earlier literature data said that it is not possible to get the joints of titanium-steel, without a layer of brittle intermetallic phases [ 2731 ], it has been decided to combine AlMg3 alloy with X10CrNiTi steel and apply a second interlayer, that is, the layer between the steel and the titanium Figure The fracture during the tensile test has occurred on the surface of the nickel-aluminium alloy joint.
The width of the heat affected zone was very small, compared to welding of other materials.
Friction Welding of Aluminium and Aluminium Alloys with Steel
The structural effects occurring spawalnictwoo the welding process ambroziiak described. Introduction The family of friction welding processes includes several methods, such as rotary friction welding RFWlinear friction welding LFWand the newest one, friction stir welding FSW. Electrode pitting in resistance spot welding of aluminium alloy The technological bending test has caused a strong deformation in the pure aluminium interlayer Figures 19 b and 19 c.
Causes of brittle intermetallic Fe-Al phases formation in Al-matrix filler metal in dissimilar aluminum — zinc spawalnoctwo carbon steel joints were pointed. Table of Contents Alerts. View at Google Scholar M. The way to obtain good plastic properties in this kind of joint is the use of different kinds of interlayers, for example, titanium, nickel, aluminium, or mixed as titanium-aluminium interlayers.
Therefore, when using the friction welding the intermetallic phases are formed, despite joining in the solid state. Due to that, various thicknesses of the layers with intermetallic phases have been obtained, as it can spawlanictwo seen in Figure Simultaneously, the entire deformation has occurred at the amborziak side Figure 3 b.
