A Metallographical Investigation on Carbide Reaction in Iron and Steel (2nd Report). On the Carbide Reaction in Chromium Steel during Isothermal Tempering

Tomo-o Sato, Hideo Kaneko and Eizo Osonoi


Abstract:

The carbide reactions in three chromium steels (c.f.Table 1) during tempering at constant temperature have been traced by measuring electrical resistance,and the mechanism of these reactions have also been confirmed by magnetic and X-ray analysises. As the results of these experiments,the following carbide reactions have been confirmed.

Steel Early stage carbide. Phase change Final forms
D (Fe, Cr)3C low Cr Dissolution of Cr into (Fe, Cr)3C (Fe, Cr)3C
E (Fe, Cr)3C (Fe, Cr)3C→(Cr, Fe)7C3 (Cr, Fe)7C3
F (Fe, Cr)3C (Fe, Cr)3C→(Cr, Fe)7C3
(Cr, Fe)7C3→(Cr, Fe)23C6
(Cr, Fe)23C6
