The paper presents our actual knowledge and experience in joining dissimilar materials with the use of friction welding method. The authors declare that there is no conflict of interests regarding the publication of this paper. Jessop has observed that the highest thickness of the intermetallic phases was present on the surface, in the distance of about half radius from the axis of the sample.

Table of Contents Alerts. Advances in Materials Science and Engineering. However, their values have been lower, probably due to the lower pressure used during the upsetting phase Table 1. The microstructure of the 42CrMo4 steel-AN40 alloy joint with the nickel interlayer a and a fragment of an enlarged microstructure of the nickel-AN40 alloy bounding zone b. In order to obtain high-quality joints the influence of different configurations of the process such as i changing the geometry of bonding surface, ii using the interlayer, or iii heat treatment was analyzed.

Another material, which has been tested as an interlayer for the joints of AlMg3 alloy-X10CrNiTi steel, was titanium. The friction welded AlMgSi0. Showing of 6 extracted citations. De Gruyter – Sciendo. The intermetallic phases had width of 3.

Using of such high diameters of the samples has been determined by the desire to achieve the ambroziam accurate approximation of the research for their utilitarian purpose. In the industry, especially in marine, ambrozoak, and refrigeration industries, the joints of aluminium alloys and chromium-nickel austenitic steel are applicable.

To obtain high-quality joint it is necessary to know and analyze phase diagram of the two welded materials. On the contact surface ajbroziak AN40 alloy-nickel, on both sides, there was a visible discontinuous intermetallic phase separation Figure 24 b.

The results of the maximum loading force, obtained in the shearing test for the investigated joints, are shown in Figure 14whereas, in Figure 15the results of shearing work, calculated for two variants of shearing patterns, andare shown.

Further attempts have been taken to obtain better properties of the 42CrMo4 steel-AN40 aluminium alloy joint, by using some interlayers, formed with friction welding too.

The microstructure in the bonding zone of the friction welded AlMgSi0. In the sapwalnictwo, especially in marine, aviation, and refrigeration industries, the joints of aluminium alloys and chromium-nickel austenitic steel are applicable. 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.

Topics Discussed in This Paper. The samples after the shearing test are presented in Figure The mechanical properties using, for example, i microhardness measurements, ambrozia, tensile tests, iii bending tests, spawalhictwo iv shearing tests were determined.

The joints of aluminium and aluminium alloys with the different types of steel were studied. Since the earlier literature data said that it is not possible to get the joints of titanium-steel, spawalnictow 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 chemical compound of the tested materials according to [ 14 ].

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. The joints, analysed spawalnoctwo the researches, have been formed with two different friction time parameters, so various thicknesses of the layers with intermetallic phases have occurred.

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.

Friction Welding of Aluminium and Aluminium Alloys with Steel

The alloying additions, which are present in aluminium alloys especially magnesium spawalnictao, usually aggravate the metallurgical conditions of aluminium bonding [ 19 ]. The presented review summarizes our actual knowledge about the friction welding of aluminium and aluminium alloys with different types of steel.

Issue 4 First Online: 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. The top surface of the steel samples has been formed with accurate sample no.

Using resistance spot welding for joining aluminium elements in automotive industry

It has been stated that the joint was characterized by efficient tensile strength, if the width of the diffusion zone with intermetallic phases was 0. The suitability of aluminium as an alternative material for abroziak bodies. Therefore, when the thickness of the intermetallic phases was 0. View at Google Scholar M.

The structural effects occurring during the welding process were amnroziak. In the case spasalnictwo welding steel to aluminium, the excessively fragile intermetallic compounds lead to the joint degradation. View of friction welded joints of Skip to search form Skip to main content. In the dissertation [ 25 ], the weldability of various aluminium alloys series, and i and S25C unalloyed carbon steel 0.

The welding of aluminium and its alloys. To investigate the influence of the parameters of the friction welding process on the shearing work some researches have been conducted [ 26 ].

Results and Discussion 2. Seli and coauthors [ 10 ] have tried to model the heat distribution during the friction welding of aluminium and structural steel and connect it with ambroziwk formation of intermetallic phases. This has been explained as a result of high spaealnictwo of deformation and an intensive mixing of the materials.
