Metallic materials will continue to have challenges related to fracture, transcrystalline,
and hydrogen embrittlement corrosion due to severe area of application that is
unavoidable. The study into the performance of metallic materials has shown that
corrosion mechanism through stress corrosion cracking often occurs vis-viz due to the
electrochemical and reduction reaction. The phase diagram is important to solve
problems related to hot corrosion, hydrogen embrittlement, intergranular corrosion,
and stresses corrosion cracking challenges. The need to look into the defining
mechanism from the researcher cannot be underestimated. These overviews provide
insight on related problem definition and formulation towards corrosion challenges and
possible assessment of the corrosion inhibitors
