Investigation on the characteristics of SS 316l alloy for repairing applications using directed energy deposition

Abstract

Hot roll steel, is one of the most popular types of steel used in newlinemanufacturing, with its versatility and durability and it has become a go-to newlinematerial for a variety of applications. Hot roll steel is a highly versatile material newlinethat has been widely used in various industries, such as construction, newlinemanufacturing, and transportation. Its strength, resilience, and affordability are newlinejust a few of its many advantages. It can withstand high levels of stress without newlinedeforming or breaking, making it ideal for use in construction projects that newlinerequire support structures. Even though the HRS material has high strength and newlinedurability, often this type of material faces surface cracks and failures in newlineoverloading conditions. Consequently, it is required to repair the spoiled part newlinewithout losing the mechanical characteristics of the part modifications. newlineIn general Arc welding is a widely used technique to repair the cracked surfaces newlineof HRS materials. In recent days the Additive Manufacturing technique is an newlineemerging manufacturing method to create metal and polymer parts by depositing newlinethe material element layer by layer. The final product will have numerous newlinethousands of thin layers (20-200and#956;m) with high precisions. Because the easy newlineapproach to creating the complex model with highly cost-effective and less newlineamount of time this AM technique has a variety of applications in the aerospace, newlinemedical, automotive, and jewellery industry. While the method has been made newlineup only polymer could be probable to employ, other than current AM methods newlinecan be employed and enhanced for numerous various materials from metals to newlineexisting cells. Adapting to this kind of emerging AM technology will give wide newlineopportunities for creating complex products with different materials like steel newlinealloys, plastics, super-alloys, high-temperature metals titanium, ceramics, etc. newlineIn conservative mechanized methods, most of the above-mentioned components newlineare also exploited. newline
