Mechanism of Formation of Vanadium Carbide Layers on Carbon Steel by Powder Packed Method
The effect of C content on the formation of V carbide layer on carbon steels by a powder packed method was investigated. The continuous duplex carbide layer consisting of an outer V2C and inner V6C5 and V8C7 layers was formed on Fe-0.7C and Fe-0.3C (in wt.%), but it was discontinuous on Fe-0.1C. Internal carbide precipitates were observed within the matrix in Fe-0.3C and -0.1C. These precipitates in Fe-0.1C were disappeared after long treatment. The inner carbide layers were confirmed to grow inwardly, which suggests that VCl2 gas can penetrate through the carbide layers to the steel substrate.
期刊介绍：
The journal ISIJ International first appeared in 1961 under the title Tetsu-to-Hagané Overseas. The title was changed in 1966 to Transactions of The Iron and Steel Institute of Japan and again in 1989 to the current ISIJ International.
The journal provides an international medium for the publication of fundamental and technological aspects of the properties, structure, characterization and modeling, processing, fabrication, and environmental issues of iron and steel, along with related engineering materials.
