The microscopic observations have proved an inhomogeneous layout of the deformed particles of stainless steel with irregular shapes surrounded by a matrix of aluminium alloy.

The microstructure of the joint is shown in Figure The deformation was observed behind the titanium layer on the AlMg3 side Figure 20 c. The friction welded AlMgSi0. The technological bending test of such joint has ended with an immediate crack which has passed the intermetallic layers Figure 7 b. The presented review summarizes our actual knowledge about the friction welding of aluminium and aluminium alloys with different types of steel.

In the first stage of the researches on the ANsteel 42CrMo4 joints, the researchers have decided to perform the friction welding on the joints, using the parameters presented in Table 1 sample no.

In the case of welding steel to aluminium, the excessively fragile intermetallic compounds lead to the joint degradation. Compared to aluminium, magnesium is characterized by a higher diffusion coefficient and has significantly lower solubility in iron.

The view of the joint after the friction welding of 42CrMo4 steel-AN40 alloy with nickel interlayer, directly after the welding aafter removal of the flash band the macrostructure of the joint c. The suitability of aluminium as an alternative material for car bodies. The results of the butt welding of X5CrNi austenitic steel and Al aluminium alloy were presented in [ 35 ]. If the period to the highest shearing force value was analysed, then the shearing work was, respectively, for the welding parameters J; J; and J Figure When the thickness was lower than 0.


For testing, they have used nonalloy carbon steel with a five times higher tensile strength than the tensile strength of aluminium. The view of a bond zone of friction welded AlMg3 aluminium alloy-austenitic steel joints light microscope, nonetched specimen, sample no.

Friction Welding of Aluminium and Aluminium Alloys with Steel

It has been stated that the joint was characterized by efficient tensile strength, if the width of the diffusion zone spawalnicgwo intermetallic phases was 0. The results of shearing work of the investigated Ambfoziak aluminium alloy-X10CrNiTi, austenitic steel joints, determined for two variants of shearing pattern according to [ 26 ].

Showing of 7 references. Until now, it has not sppawalnictwo possible to obtain any welded joints of chromium-nickel austenitic steel with AlMg3 aluminium alloy, with sufficient plastic properties for direct joining. For the material of this layer the pure Al View of friction welded joints of AlMgSi0.

On the contact surface of AN40 alloy-nickel, on both sides, there was a visible discontinuous intermetallic phase separation Figure 24 b. The technological bending test has caused a strong deformation in the pure aluminium interlayer Figures 19 b and 19 c.

On the base of the previous researches on the diffusion welding process [ spawalnicrwo30 ], the nickel has been selected. Wherein, the highest values average of The samples of aluminium alloy have been additionally etched and then washed in ethyl alcohol again. Results and Discussion 2.

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.

The researches on the shear energy of the joints have determined its dependence on the thickness of the intermetallic phases. View at Scopus T.

However, recently, the most important seems to be the possibility of joining materials with different properties. Equilibrium diagram for the aluminium-iron system according to [ 15 ]. In the dissertation [ 34 ], some examples of welding the AA aluminium alloys with SS low carbon steel were presented. The authors declare that there is no conflict of interests regarding the publication of this paper. While for joints, which have been friction welded with low friction time, there was a continuous narrow diffusion zone with a diameter of few micrometers Figure 13 a ; 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.

But the alloying additions, which are present in aluminium alloys especially magnesiumusually aggravate the metallurgic conditions of aluminium bonding.

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. There have been attempts of increasing the diffusion interaction on the surface of the ANCrMo4 steel joint, by additional annealing of spawanictwo joint in the diffusion welder.
