Abstract Scope |
Recently, there has been interest within the automotive industry in a heat treatable, high strength, low alloy steel powder for use in additive manufacturing technologies. 4130 is a chromium and molybdenum containing alloy that can be produced in powder form. In this study, rods of 4130 alloy were produced using laser powder bed fusion under optimized process parameters. The samples were then heat treated according to different profiles. Metallographic analysis was performed to determine the different phases present at different heat treatments. Hardness and tensile data was also collected and compared. The goal was to gain a comprehensive understanding of the properties of this material under different conditions to provide design guidance for future applications. |
