Based on the idea of alloying welding seams, a series of Zn-xAl filler metals was calculated and designed for joining Mg/Al dissimilar metals by gas tungsten arc (GTA) welding. An infrared thermography system was used to measure the temperature of the welding pool during the welding process to investigate the solidification process. It was found that the mechanical properties of the welded join...

This paper describes the results of work on the feasibility of using high frequency ultrasound to determine .the degree of bondedness of multilayer structures. A sandwich structure of two identical metal sheets of thickness on the order of 25 ~m, bonded together by a dissimilar third layer of thickness 10 ~m was examined. The primary disbond was expected to be in the region of the interface bet...

Composite nanoarchitectures represent a class of nanostructured entities that integrates various dissimilar nanoscale building blocks including nanoparticles, nanowires, and nanofilms toward realizing multifunctional characteristics. A broad array of composite nanoarchitectures can be designed and fabricated, involving generic materials such as metal, ceramics, and polymers in nanoscale form. I...

In this study, arc and friction stir hybrid welding (AFSHW) was proposed to weld aluminum-steel dissimilar metals in attempt realize high quality joining. Firstly, an interlayer produced on galvanized steel by using bypass current-metal inert gas (BC-MIG), then aluminium plate jointed via Friction lap (FSLW). The effects of tool pin length FSLW times the microstructure mechanical properties joi...

mechanical properties of dissimilar weld joints between gost09ch16n4b (a martensitic stainless steel) and aisi 4130 thin sheets made by gas tungsten arc welding (gtaw) were studied using er410nimo and er100s-g filler metals in post weld heat treated conditions. heat treatment cycles consisted of austenitization at 900, 950 and 1000 °c for 1 h and this was followed by oil cooling and tempering a...

The 5052 aluminium alloy and 304 stainless steel were successfully joined by cutting-assisted welding-brazing (CAWB) method without using flux. Dual-scale interfacial structures achieved designing the geometry of cutting tool. Results indicated that macroscale self-locking interface was produced when taper step-shape tool adopted. Especially step increased to 6 steps, microscale took on a micro...
