A Metallographical Investigation on Carbide Reaction in Iron and Steel (1st Report). On the Carbide Reaction of Chromium Steel during Isothermal Heating

Tomo-o Satô, Hideo Kaneko and Eizo Osonoi


Abstract:

Carbide reactions in following three chromium steels after isothermal transformation have been studied by measuring electrical resistance and Curie points of carbides.

C (%) Cr (%) Phases in equilibrium
Steel-A 0.98 0.55 α+θ
Steel-B 0.33 4.29 α+η
Steel-C 0.38 13.28 α+ε


During the isothermal transformation of these steels, θ-phase carbide containing low Cr is formed, and it dissolves Cr to equilibrium content after the transformation. In steels B and C, the saturated θ-phase changes its form by carbide reaction as listed in the next table.
