Bismuth (Bi) metallic material is one of the most widely used heavy metals because of its low cost, excellent light conversion efficiency, and high X-ray attenuation coefficient. However, large-scale synthesis of highly processable and oxidation-resistant Bi nanoparticles remains challenging. Based on the above concerns, we report a facile, scalable, polyol-mediated synthesis of high-quality Bi nanoparticles using citrate as a capping agent and polyvinylpyrrolidone (PVP) as a dispersant. The presence of citrate and PVP improved Bi nanoparticle's oxidation resistance and processability. These nanoparticles can maintain excellent oxidation resistance in an ambient atmosphere for more than 120 days and form high-quality suspensions in various commonly used solvents. Moreover, large-scale and rapid synthesis of the nanoparticles was achieved by simply using the green reagent stannous citrate [tin (II) citrate] as a reducing agent. These properties make them promising as complementary conductive fillers in electrically conductive adhesives (ECAs). The Bi nanoparticles could be effectively combined with silver flakes in epoxy resins to enhance the conductivity of ECAs significantly. With the addition of only 5 wt % Bi nanoparticles, the resistivity of ECAs could be reduced to 1/3000 of that of ECAs with the same silver content, showing great promise in next-generation ECA products.

“…The TWBs are commonly fabricated via laser welding. Recently, the tensile strength of laser tailor welded DP980 and 22MnB5 was found to increase by 75% upon hot forming [5]. Upon laser welding of interstitial free (IF) steel and high strength low alloy (HSLA) steel, though the failure took place on the IF side for the uniaxial tensile tests, the failure due to thinning upon deep drawing occurred on the HSLA side owing to its low mean plastic strain ratio [6].…”

This article serves as a compendium to the design engineers proceeding to manufacture geometrically complex functional components having an array of mechanical properties owing to a variety of metallic materials that are welded together. Such dynamic attempts require the knowhow of forming behavior of welded sheet metals, which are carefully explicated based on recent advances. The thickness and/or strength dissimilarity across the welded microstructures give birth to distortion and warpage in the welded sheets. The warpage during the forming operation renders the workpiece useless. The modern approaches to tackling the warpage phenomena like weld line movement and springback are highlighted with emphasis on unification of finite element, artificial neural networks, genetic algorithms, and analytical methods. This is necessary for the free form forming operations on welded sheets to provide creative edge and flexibility in design. Significance statementThis work provides a multitude of solutions for the formability issues in free forming of tailor welded blanks through meticulous study of recently published literature. The decrease in production lead times, consumption of resources, waste generation, etc. can be simultaneously achieved with an increase in part complexity in the manufacturing industry through the current study.
