| Abstract Scope |
This study investigates the relationship between CrB intermetallic phase content and the mechanical properties of boron-added 316L stainless steel produced via additive manufacturing. A Taguchi experimental design was employed to systematically vary process parameters, including boron content, feed rate, laser power, and scan speed. CrB phase formation was quantified using image processing based on intensity contrast, and the resulting data were correlated with tensile strength and Vickers microhardness. The analysis revealed that excessive CrB formation had a detrimental effect on mechanical properties, emphasizing the importance of optimized processing conditions. Signal-to-noise (S/N) ratio analysis was conducted to evaluate the significance of each parameter and identify conditions that minimized harmful phase formation while maximizing mechanical performance. This study demonstrates the integration of microstructural image analysis and statistical design of experiments as an effective approach for optimizing additive manufacturing processes in complex alloy systems. |
