Alloy Cast

Cast irons are basically binary alloys of iron and carbon having carbon exceeding its maximum solid solubility in austenite but less than the carbon content of iron carbide. However, like steels, cast irons have varying quantities of silicon, manganese, phosphorus and sulphur. Silicon plays an important role in controlling the properties of cast irons and for this reason, the term cast iron is usually applied to a series of iron, carbon and silicon alloys. Special purpose cast irons include white and alloy cast irons which are mainly used for applications demanding enhanced abrasion, corrosion or heat resistance. In present study, corrosion resistant cast irons are of our interest.

The finite element method (FEM) was used to simulate the sliding wear progress. The stress field and strain field of Cr-Mo-Cu alloy cast iron with nano-additives under wear abrasion were analyzed through experiment and numerical investigation in this paper. And then the wear depth was got by calculation for different alloy cast irons by taking graphite morphology into account. The graphite morphology was changed by addition of nano-additives, with the aspect ratio of graphite was transformed from 2 to 10, three kinds of graphite aspect ratio prepared including 2, 5 and 10.

Cast irons belong to a family of iron-carbon (Fe - C) alloys with free carbon in the form of graphite, a very soft constituent of iron microstructures, that improves machinability and damping properties of castings, or combined carbon, in the form of cementite, that improves wear resistance. Graphitic cast irons include grey iron, compacted iron, malleable iron, and ductile iron, Cementite irons include white cast iron and alloy cast irons. Solidification of graphite directly from molten metal takes place between 1145°C (2093 °F) and 1152 °C (2105 °F), according to the Fe-C equilibrium diagram. The above considerations regard only pure Fe - C alloys.

Alloy Cast

An alloy cast iron has special properties by adding some alloying elements to the ordinary cast iron ASTMNo35A. Diffusion wear is one of the main cutting tool wear mechanisms in machining of the alloy cast irons. The diffusion of tungsten (W) and iron (Fe) between the alloy cast iron and the WC/Co cemented carbides was investigated in this paper by means of heating diffusion couple. It has be proved from the experiment that Fe in the alloy cast iron diffused a deeper distance in the WC/Co cemented carbides with the higher Co content; while the diffusion of W element in the WC/Co cemented carbides the alloy cast iron was not serious. The Vickers-hardness analysis of the alloy cast iron and K20 cemented carbide couple was determined. The elements diffusion impaired the hardness of the alloy cast iron and WC/Co cemented carbide cutting tool.

Summary In many recent publications on the optimisation of alloys in terms of, among other things, their strength and resistance to wear, a trend can be observed to look for new alloying additives to improve these properties. This paper presents the results of a study on the effect of changes in the chemical composition of EN-GJS-500-7 ductile alloy cast iron on its mechanical properties. In order to confirm the effect of alloying additives on the mechanical properties of the alloys, industrial melting of cast iron was carried out and samples were taken for testing. The smelts were not subjected to heat treatment, but were carried out differently in terms of the feedstock used and based on the analysis of the cooling curve using an automated smelting technology enabling the elimination of degraded Chunky graphite. The influence of the shape of graphite precipitates on tensile strength and hardness was determined, and spectroscopic studies of the microstructure of cast irons were carried out.

Alloy Cast

In allusion to facility corrosion problem in caustic soda industry five types of ni-Cr-cu alloy cast irons were developed. The corrosion rates of ni-Cr-cu alloy cast irons in hot concentrated alkali solution were measured by using self-made dynamic corrosion experiment equipment; the microstructures and surface corrosion morphology of alloy cast irons were observed by means of the optical microscope and SEM; the composition was analyzed using XES. Corrosion resistance mechanism were discussed detailedly. the experimental results showed that ni-Cr-cu cast iron was uniform corrosion macroscopically in the dense caustic soda at high temperature and there was ni, cu enrichment microcosmically. The Ni and Cu enriched in the matrix , which increase in local electrode voltage of the matrix,are advantageous to the improvement of caustic corrosion resistances of that zone. The higher Ni content,the better alkali corrosion resistance performance with high temperature.
