Research Progress on Control Strategy of Intermetallic Compounds in Welding Process of Heterogeneous Materials

Abstract

Since the beginning of the 21st century, countries around the world have continuously increased their efforts in environmental governance. It has higher requirements for the performance of materials, not only to ensure that it is clean and nonpolluting, but also to maximize benefits. The mechanical properties and economic value of a single material can no longer meet the production needs of enterprises. Therefore, more people use composite materials to replace single materials. The use of composite materials not only can effectively respond to the concept of green development, but also reduces cost input to a lager extent. The composite of dissimilar metals can volatilize the respective advantages of the two materials. Common materials can be used to replace rare metals to reduce the use of precious metals. [1][2][3][4] World-renowned automobile companies such as Japan's Toyota and Honda are vigorously researching lightweight production technologies. Lightweight alloys (such as magnesium [Mg] alloys, aluminum [Al] alloys, etc.) could be used in place of steel in non-load-bearing structures. Mg alloys are one of the lightest metal materials so far, with a density of only 1.74 g cm À3 , which is about 2/3 of Al, 1/4 of zinc, and 1/5 of steel. They have high specific strength, specific stiffness, good damping performance, and easy recycling and other advantages, known as the "21st century green engineering metal materials." Titanium (Ti) alloy is expensive and its processing performance is relatively poor. Steel has

Evaporate-casting of curvature gradient graphene superstructures for ultra-high strength structural materials

“…5h , Supplementary Figs. 27 and 28 ), comparable to welded metals 23 , 24 , and far superior to various types of connectors including self-healing polymer 25 – 27 , and 3D printed structures 28 – 30 (Supplementary Table 1 ). Energy utilization can also be calculated through the thermal transfer power during the material preparation process, and the mechanically interlocked structure exhibits values that are 1 to 4 orders of magnitude higher than those of the aforementioned contrast materials (the calculation of energy utilization is detailed in Supplementary Information).…”

Dataset of manual metal arc welded heterogeneous thin steel plates AISI1018 AND AISI4340

“…With the advancement in technology, always there will be a call for heterogeneous metal welding, especially in the engineering material steel alloys [1] , [2] , [3] , [4] . The steel alloy AISI1018 is the most commonly used and cheap steel grade in the fabrication industry for making doors, window grills, and stair guards [5] .…”

Kinetics of Nickel Diffusion into Austenitic Stainless Steels AISI 304 and 316L and Calculation of Diffusion Coefficients

“…However, the creation of heterogeneous joints increases the risk of the formation of intermetallic phases, which are brittle and decrease the strength of the joints [3]. The formation of intermetallic phases can be eliminated by using interlayers [4]. The joining of titanium and stainless steel has been studied, for example, by scientists from India, and their results were published in [5].…”
