Intermetallic FexAly-phases in a steel/Al-alloy fusion weld

Optimization of RSW parameters by joining galvanized steel HZ 220 BD-Z100 MB with aluminium AV 1050A

“…No zinc from the steel sheet surface was identified in the reaction zone, which is consistent with the results published in the paper [19]. A transition zone, consisting predominantly of intermetallic compounds of the Al x Fe y type, was analysed in detail, for example, in [8]. The SEM of the reaction zone of sample 7 (see Table 6) is shown in Fig.…”

“…the joints [7,8,17,18]. Of course, they are also affected by the occurrence of defects at the interface between sheets, such as pores and lack of fusion (Figs.…”

Influence of Filler Alloy Composition and Process Parameters on the Intermetallic Layer Thickness in Single-Sided Cold Metal Transfer Welding of Aluminum-Steel Blanks

“…[9][10][11] An opportunity for joining particularly thin metal sheets by combining the advantages of both fusion and solid-state welding offers the Cold Metal Transfer (CMT) process developed by Fronius. [12] The CMT process enables spatter-free joining of similar metals, e.g., Al-Al bead-on-plate [13][14][15] or butt welding, [16] as well as joining of dissimilar metals, e.g., Al-steel butt welding with tapered steel sheet edges, [17][18][19] overlap welding, [20][21][22][23][24][25][26][27][28][29] or even spot welding. [30][31][32] In comparison with conventional gas metal arc (GMA) welding processes, the heat input of the CMT process is significantly reduced.…”

Efeito dos parâmetros de processo na obtenção e na microestrutura de juntas alumínio-aço realizadas mediante soldagem por atrito com pino não consumível (SAPNC)

“…A junção destes materiais por meio dos processos tradicionais de soldagem resultam na formação de compostos intermetálicos (CIM) do tipo Fe x Al y [1]. Processos como a soldagem a laser, difusão, ultrassom e laminação já foram empregados com resultados promissores, entretanto persiste a formação dos CIM.…”
