Influence of normalizing and tempering treatment on microstructures and mechanical properties of reduced activation ferritic-martensitic steel fabricated by laser directed energy d... by Zhichen Wang, Linjiang Chai, Shuangshuang Zhong, Chaodan Hu, Tao Yang, Yi Tang, Yu Wu, Xiaolian Tan, Peng Song, Hao Yu, Korukonda L. Murty

“…Reduced activation ferritic-martensitic (RAFM) steel with high strength was prepared by utilizing laser directed energy deposition (L-DED) technology, followed by normalizing and tempering (N&T) to enhance ductility and toughness with underlying mechanisms unraveled through detailed microstructural analysis. Owing to ultrafast heating and cooling features in laser processing, the L-DEDed specimen exhibits a complicated heterostructure, including ultrafine martensite with high-density of dislocations, a small amount of retained δ-ferrite and austenite, and a few second-phase particles at grain boundaries. …”
