“…A baixa intensidade difratada pela cementita Fe 3 C foi atribuída a baixa fração volumétrica deste composto nas amostras analisadas e pode sugerir que o carbono adicionado durante a produção das varetas Ti, Ti-Cr e Ti-Nb foi suficiente para a formação dos carbonetos ricos em titânio. No aspecto qualitativo especula-se que as partículas morfologicamente grandes e não excessivamente facetadas seriam mais indicadas para compor um revestimento resistente à abrasão, pois a distribuição de tensões durante o desgaste seria melhor distribuída [17,18]. A fragmentação dos carbonetos pode ocorrer durante o desgaste, fazendo com que estas atuem como partículas abrasivas em movimento.…”

“…Increasing the chromium content changes the structure and properties of chromium carbides from M 3 C to M 7 C 3 or M 23 C 6 -where M is Cr, Fe and other elements that may be bonded in carbides [6][7][8][9][10]. Not all carbides have a similar morphology [11,12].…”

“…Occasionally, however, following the example of eutectic carbides, they tend to form a continuous network in the interdendritic spaces. Carbides of the M 3 C and M 23 C 6 type occur as interconnected fibres or plates [5][6][7][8][9][10][11][12][13][14]. Isolated carbides are more effective in suppressing cracks in a ferritic matrix where they are easily embedded.…”

The results of studies of the effect of different amounts of the Fe-Ti inoculant on structure and selected mechanical properties of High Chromium Cast Iron (conventionally abbreviated as HCCI) are presented. The main purpose of the inoculation is structure refinement and hence the improvement of casting properties. Generally considered a strong carbide-forming element, titanium is an effective inoculant for the high chromium cast iron. However, there is an optimal amount of titanium addition beyond which the mechanical properties begin to deteriorate. The studies enabled determining the amount of Fe-Ti inoculant optimal for the cast iron of a given chemical composition.

“…Manganese seem to be most promising alternative to be used as it also austenitic promoter despite manganese also suspected to interrupt with the nodularisation during solidification [17], acts as sulphur controller [18] and also well known as carbide promoter [19][20][21]. Although some of the nickel in these alloys can be replaced by manganese, the structure will still remain austenitic matrix.…”

Abstract. The effect of manganese addition and annealing heat treatment on microstructure of austenitic cast irons with high manganese content (Mn-Ni-resist) were investigated. The complex relationship between the development of the solidification microstructures and buildup of microsegregation in Mn-Ni-resist was obtained by using microstructure analysis and EDS analysis. The annealing heat treatment was applied at 700°C up to 1000°C to investigate the effect of the annealing temperature on the microstructure. This experiment describes the characterization of microsegregation in Mn-Ni-reist was made by means of point counting microanalysis along the microstructure. With this method, the differences of silicon, manganese and nickel distribution in alloys solidified in the microstructure were clearly evidenced. The results show microstructure consists of flake graphite embedded in austenitic matrix and carbides. There is segregation of elements in the Late To Freeze (LTF) region after solidification from melting. Manganese positively with high concentration detected in the LTF region. As for heat treatment, higher annealing temperature on the Mn-Ni-resist was reduced carbide formation. The higher annealing temperature shows carbide transformed into a smaller size and disperses through the austenitic matrix structure. The size of carbide decreased with increasing annealing temperature as observed in the microstructure.
