By precisely controlling the alloy composition, heat treatment schedule, and microstructure, it becomes possible to tailor materials to meet specific performance requirements for a wide range of applications.

Through investigating the influential factors on brittle fracture, such as alloy composition, segregation, precipitation, it enhances understanding of the mechanisms underlying steel’s susceptibility to brittle fracture.

The utilization of advanced characterization techniques, such as TEM, FE-SEM(EPMA, EBSD), APT for multi-scale linking, assists in elucidating unknown mechanisms associated with surface reaction (oxidation, blister) or strengthening processes(dislocation interaction with solute, precipitation).
