Customer ServiceThe production of such resistances involves joining processes of amorphous ribbons. The amorphous alloys are difficult to weld by conventional melting processes, even in the presence of inert gas.

Customer ServicePost-weld heat treatment (PWHT) serves to mitigate residual stress within the weld, refine grain structure, elevate the quality of the joint connection, and ultimately bolster the joint's strength , so it is essential to perform PWHT for IRW joints. Numerous researchers have conducted investigations on steel-aluminum transition joints.
However, the dissimilar physical and chemical properties of steel and aluminum result in the development of a specific thickness of Fe-Al Intermetallic compounds (IMCs) during IRW. This can lead to the formation of cracks surrounding the weld, consequently impacting the overall strength of the joint.
Heat treatment process of induction roll welded steel-aluminum transition joint. The IMCs consist of the tongue phase Fe 2 Al 5 and the serrated phase FeAl 3. Repaired the crack in the joint and refined the grain size of the joint. Improved mechanical properties of the joint were achieved.
The study assessed the influence of PWHT on the microstructural characteristics and mechanical properties of the steel and aluminum IRW joint through an examination of alterations in IMCs thickness, types, hardness, and tensile strength of the joint before and after heat treatment.
Comparing the shear strength under different annealing processes, it is evident that the shear strength of IRW joints annealed at 200 °C and 300 °C for varying times and annealed at 400 °C for 1 h, increased to a certain extent compared with that of the as-welded specimens.
The influence of time on IMCs thickness was not significant during the observation period, but at an annealing temperature of 500 °C, the IMCs thickness at 25 min was twice that at 5 min. Dong et al. conducted a study on the impact of PWHT on the rotary friction welded joint of 5052 aluminum alloy and 304 stainless steel.
