Redistribution Of Chromium Research Articles

Effect of diffusional redistribution of chromium on the wear resistance of carburized steel 3Kh13

1. Carburizing of high-chromium steel with high carbon concentrations in the case leads to redistribution of chromium in the case. 2. With the same carbon concentration, the wear resistance is higher for the case with a larger chromium concentration and correspondingly larger quantily of special Cr7C3 carbides, the wear resistance of which is higher than that of carbides of the cementite type.

Redistribution of nickel and chromium during the? ?? transformation in Cr?Ni stainless steels

1. In Cr−Ni martensitic steels with 11% Cr and 9% Ni the α→γ transformation at heating rates below 50 deg/sec is accompanied by redistribution of chromium and nickel between the α and γ phases. 2. The austenite formed in the partial α→γ transformation contains more chromium, nickel, and probably more molybdenum than the α phase. 3. The enrichment of austenite in chromium, nickel, and other elements in the process of the α→γ transformation in steels of the Kh11N9 type is evidently one reason for the stabilization of austenite during tempering of these steels at α→γ transformation temperatures.
