Refining the hierarchical structure of lath martensitic steel by in situ alloying with nickel: morphology, crystallography, and mechanical properties

Lath martensitic high-strength steels are some of the most widely used materials in structural applications, and consequently, refining and controlling the lath martensitic morphology is of significant interest to expand the versatility of the steels and their associated range of applications. It is well known that the steel’s carbon content has a pronounced effect on the lath martensitic morphology, its crystallography, and hierarchical …
