In recent years, in contrast with conventional welding methods, ultrasonic welding has been one of great importance among its relevant applications and materials. The bonding of different materials is always difficult, as the unregulated scale of the grain and the fragile mechanical properties are different than conventional welding techniques. In addition, this research paper offers numerous explanations and uses of the ultrasonic welding technique on different materials and its alloys such as aluminium, steel, titanium, nickel, magnesium and also on fiber reinforced composites and thermoplastics along with their mechanical properties. The key benefits of this method are also discussed such as clean and undamaged welding on outer sections, reliable and solid bonding, and saves time effectively.
The reinforced Metal Matrix Composite (MMC) was broadly used in various engineering applications. The light weight and high strength metal matrix components were used in aerospace and automotive applications. The silicon carbide, boron carbide, aluminum oxide and carbon fiber were used as common reinforcement materials. The magnesium and its alloys were recently has a maximum role in MMC due to its high strength and light weight. In addition to the magnesium, the aluminium and copper was included through the reinforcement of boron carbide (B4C). It was formulated through squeeze casting technique. The copper has good electrical conductivity and it has more corrosion resistance. The magnesium metal matrix was fabricated through squeeze casting technique. The Vickers hardness was determined through the different input squeeze casting factors such as pressure, pouring temperature and die temperature. The Response Surface Methodology (RSM) optimization was used to analyze the parametric effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
