Introduction The concept of functionally graded materials (FGMs) was proposed in 1984 by materials scientists in the Sendai area of Japan as a means of preparing thermal barrier materials [1].
The fracture behavior of materials is primarily determined by the local stress field around the crack front.
Furthermore, the local stress field is related to the microstructure of materials.

The research results show that, hot metal carbon oxidation rate and vanadium oxidation rate increased with the increased use of cold briquetting ores, and the TFe content of vanadium slag reduced, the consumption of iron and steel materials decreased.
Experiments Use dust produced by steelworks (dust from vanadium-recovering converter and steel-making converter) and oxide scale from hot-rolling plant as raw materials, whose ingredients are shown in Table 1, oxide scale from hot rolling mill play as aggregate to produce cold briquetting ore of the diameter 35 ~ 45mm.
