Effect of interlayer temperature on the microstructure and mechanical properties of ultra-high-strength steel fabricated by ultrasonic impact-assisted wire arc additive manufacturing.
This study investigates the microstructure and mechanical properties of 14Ni3Cr3Mo2Mn ultra-high-strength steel components fabricated by ultrasonic impact-assisted wire arc additive manufacturing (UI-WAAM) at four interlayer temperatures: 80 °C, 150 °C, 200 °C, and 300 °C. Results reveal that interlayer temperature non...
