“…4). Be added as the austenite stabilizing element, nickel with its small amount does not change the microstructure of the as-cast Hadfield steel [21]. Carbide forming elements, such as chromium, enhance the formation of the complex carbide ((Fe, Mn, Cr) 3 C), which blocks the growth of the austenite grain and refines the structure.…”

In this study, the effect of heat treatments on the microstructure and wear resistance of Hadfield steel with different Cr + Ni contents is investigated. Hadfield steel with 1.2% wt. C and 12% wt. Mn is melted in an electric arc furnace. Added elements (Cr and Ni) are crushed and added as ultra-fine powders of ferro-alloyed composition in a well heated ladle. Two series of heat treatments are applied: one at 1100°C and the other at 1050°C. The microstructure of these steels is analysed using optical microscopy, scanning electron microscopy and X-ray diffraction. The Rockwell C hardness and the Vickers microhardness are measured at ambient temperature. The wear behaviour of all samples in as-cast and heat treated states is studied using pinon-disk wear tests. The obtained results show that the microstructure of the as-cast Hadfield steel samples consists of an austenitic matrix and complex carbides precipitated at the grain boundaries. Increase in the Cr + Ni content refines the structure that improves the hardness and the wear resistance. In the heat-treated state, the microstructure reveals two distinct phases: martensite and retained austenite. The increase of heat treatment temperature favours the martensitic transformation, which positively affects the hardness and wear behaviour of studied steels.

Metal alloys with matrix based on an Fe-Al system are generally considered materials for high-temperature applications. Their main advantages are compact crystallographic structure, long-range ordering and structural stability at high temperatures. These materials are based on an intermetallic phase of FeAl or Fe3Al, which is stable in the range from room temperature up to the melting point of 1240°C. Their application at high temperatures is also beneficial because of the low cost of production, very good resistance to oxidation and corrosion, and high mechanical strength. The casting alloy the structure of which includes the FeAl phase is, among others, highaluminium cast iron. This study has been devoted to the determination of the effect of vanadium and titanium on the transformation of the high-aluminium cast iron structure into an in-situ FeAl-VC composite.

The MeThod of InoculaTIon of hIgh-QualITy grey casT Iron InTended for MassIve casTIngs for BoTToM and dIsTance PlaTes as Well counTerWeIghTs ManufacTured as verTIcal casTIngsThe technology of producing castings of high-quality inoculated cast iron with flake graphite particles in the structure is a combination of the melting and inoculation process. Maintaining the stability of the strength and microstructure parameters of this cast iron is the goal of a series of studies on the control of graphitization and austenitic inoculation (increasing the number of primary austenite dendrites), and which affects the type of metal matrix in the structure. The ability to graphitize the molten alloy decreases with its holding in the melting furnace more than an hour. The tendency to crystallize large dendritic austenite grains and segregation of elements such as si, ni and cu reduce the ductility properties of this cast iron. The austenite inoculation process may introduce a larger number of primary austenite grains into the structure, affecting the even distribution of graphite and metal matrix precipitation in the structure. Known inoculation effects the interaction (in low mass) of additives: sr, ca, Ba, ce, La, produces MC 2 carbide). Addition of Fe in the inoculant influences the number and shape of austenite dendrites. Hybrid modification combines the effects of these two factors. The introduction of nucleation sites for the graphite eutectics and primary austenite grains result in the stabilization of the cast iron microstructure and an increase in mechanical properties. The obtained test results set the direction for further research in this area in relation to the production of heavy plate castings in vertical and horizontal pouring.
