Intermetallic Phase Formation in Explosively Welded Al/Cu Bimetals

Experimental Analysis and Mathematical Model of FSW Parameter Effects on the Corrosion Rate of Al 6061-T6-Cu C11000 Joints

“…The selection of the parameters employed in the FSW was based mainly on experience and the reported experimental results. Different investigations in which Al 6061 and commercially pure Cu were joined [16][17][18][19]25,39] obtained quality joints. The plate thickness, the welding parameters and the configuration used vary with a traverse speed from 30 to 100 mm/min and a rotational speed from 710 to 1500 rpm.…”

“…Nevertheless, due to the differences in metallurgical and mechanical properties between copper and aluminum, their joining represents a challenge; however, such joints have recently been achieved via FSW, and this is now one of the main techniques under investigation in this area [16][17][18][19][20][21][22][23][24][25][26][27]. The main applications of Al-Cu joints are as conductors in transformers, electrical connectors, busbars, heat exchanges, etc., combining the electrical conduction capacity of copper and the heat dissipation capacity of aluminum [19,20,28].…”

“…In addition, FSW has relevant industrial applications in the automotive, aerospace, railway, nuclear and chemical industries [1,7,8]. FSW has become one of the most successful methods of joining different materials, such as Al-Mg [9,10], Al-Ti [11,12], Al-Fe [13][14][15] and Al-Cu [2,4,5,7,[16][17][18][19], wherein physical, chemical, and thermal factors greatly influence the heat generated during the process, as well as the flow of materials, the microstructures, and the final mechanical properties of the weld.…”

Cu/Al levhaların sürtünme karıştırma kaynağında Taguchi metodu ile çekme mukavemeti ve sertlik için optimum kaynak parametrelerinin tahmini

“…Elektrik elektronik endüstrisinde ve özellikle yüksek doğru akım hatlarında, bu iki metalin sağlam bir şekilde birleştirilmesinde farklı kaynak yöntemlerinin uygulanabilirliği hakkında yoğun çalışmalar yapılmaktadır [12]. Bakırın alüminyum ile birleştirilmesinde sürtünme kaynağı [13], patlama kaynağı [14], lazer kaynağı [15], ultrason kaynağı [16], difüzyon kaynağı [17] [25].…”

Influence of base material properties on copper and aluminium–copper explosive welds

“…Athar and Tolaminejad [11] and Amani and Soltanieh [12] studied the interaction of the Al–Cu couple during EXW and found that intermetallic regions are easily formed at the interface of the welds. These regions are composed of Cu x Al y intermetallic phases, which are very hard and brittle, and have a detrimental effect on the mechanical behaviour of the welds.…”
