Abstract
En 中文
• Scanning strategy optimization reduced porosity in overlapping regions by over 80.0%. • The scanning strategy was identified as a key factor governing microstructure evolution. • Mechanical properties were tailored by scanning strategy, with tuning ranges over 25% in strength or 100% in elongation. • The mechanical tailoring strategy was validated across three alloy systems.
