| Abstract Scope |
The design and fabrication of forging preforms are crucial for achieving defect-free metal flow and minimizing material loss. Traditional forging processes involve multiple preforming steps, leading to higher tooling costs, extended lead times, and significant thermo-mechanical processing. Additive Manufacturing (AM) offers a transformative approach by enabling the production of complex preforms in fewer steps, reducing costs and energy consumption.
This study investigates the uniformity of microstructure and mechanical properties in SLM-printed 316L stainless steel and Inconel 718 preforms. Samples from the corner, face center, and body center were analyzed using X-ray diffraction (XRD), optical microscopy, and scanning electron microscopy, revealing consistent microstructures across locations. Mechanical evaluations, including density measurements, hardness, tensile testing, and ultrasonic testing, demonstrated high relative density (>99%), enhanced hardness, superior strength, and uniform wave speed. These findings confirm the feasibility of implementing AM-printed preforms for forging applications, ensuring uniform properties critical for industrial adoption. |
