The Effect of Metallurgical Mixing Method on Micro Structure, Mechanical Properties, and Electrical Conductivity (Cuni) - 5WT.%MO - 4WT.%SIC

In the industrial sector, electrical discharge machine (EDM) is one of the most widely used non-traditional cutting methods, mainly because of its ability to work on very hard conductive materials. The process of cutting EDM is very dependent on the electrodes used. An ideal EDM electrode must have several characteristics, including high melting points, good electrical conductivity, high density, good thermal conductivity, ease of processing, and low costs. However, one type of material alone cannot meet all of these requirements. Therefore, this study examines the characteristics of the alloy (cuni)-5WT.% Mo-4WT.% SIC as EDM Electrodes using three variations of powder metallurgical mixing methods: Horizontal Milling, V-Mixer, and Mechanical Alloying.

The Importance of Selection of Mixing Methods in the Production Process

The selection of mixing methods in powder metallurgy is a crucial step in producing high-quality materials with desired properties. The method of mixing can significantly affect the microstructure, mechanical properties, and electrical conductivity of the final product. In this study, we investigated the effect of three different mixing methods on the properties of the cuni alloy. The results show that the mechanical alloying method produces specimens with the best mechanical properties, including high density, hardness, and electrical conductivity.

Mechanical Alloying Method: A Key to Producing High-Quality Materials

The mechanical alloying method is known to produce fine particles and distribute materials evenly, which allows for better binding during the sintering process. This method produces specimens with a density of 5.65 gr/cm³, hardness of 65.1 VHN, and maximum voltage at a load of 20 tons reaches 387.42 MPa. The electrical conductivity was recorded at 3.590 × 10⁷ to M, and the crystal size reached 24.68 Nm. These results indicate that the mechanical alloying method is effective in producing high-quality materials with desired properties.

Horizontal Milling and V-Mixer Methods: A Comparison

In contrast to the mechanical alloying method, the horizontal milling and V-mixer methods produce specimens with lower mechanical properties. The density of the specimens produced by these methods is lower than that of the mechanical alloying method, and the hardness and electrical conductivity are also lower. These results suggest that the horizontal milling and V-mixer methods are not as effective as the mechanical alloying method in producing high-quality materials.

Microstructure: A Key Factor in Determining Mechanical Properties

The microstructure of the material is a critical factor in determining its mechanical properties. The small crystal size (24.68 Nm) produced through the mechanical alloying method contributes to the increase in material strength through the effect of strengthening grain size. With grain size control, material can show higher resistance to deformation and wear during the cutting process.

Electrical Conductivity: A Critical Factor in EDM Applications

Electrical conductivity is a critical factor in EDM applications, as it affects the efficiency of the cutting process and the durability of the electrodes. The high electrical conductivity of the specimens produced by the mechanical alloying method is promising for EDM applications. With good conductivity, electrodes can last longer and reduce the required replacement frequency.

Conclusion

In conclusion, the selection of mixing methods in powder metallurgy is a crucial step in producing high-quality materials with desired properties. The mechanical alloying method is effective in producing specimens with high density, hardness, and electrical conductivity. The results of this study open the way for further innovation in the development of EDM electrode materials, which has the potential to increase the efficiency and effectiveness of the cutting process in various industrial sectors.
