Dissolution of chromium carbide Cr3C2 in Kh17N2 steel during sintering

Powder Metallurgy and Metal Ceramics Aims and scope

The effect of sintering temperature (900–1300°C) on the interaction of Cr3C2 with a Kh17N2 steel matrix is studied. It is shown that complex iron–chromium carbide of (Cr, Fe) x C y type forms during sintering. With increasing temperature, it undergoes a number of phase transformations. The following mechanism of Cr3C2 dissolution in the steel matrix is established: Cr3C2 → 900°C (Cr, Fe)2C → 1050°C (Cr, Fe)7C3 → 1200°C (Cr, Fe)23C6 → 1300°C (Cr, Fe)2C.
