“…Graphite ratio with inoculant ratio and section thickness Based on the data obtained from the image analysis and Figure 8, the main effect plots were drawn which can be seen in Figure 9. Section thickness has a clear effect on graphite thickness and graphite length whereas the critical amount of inoculant appears to be 0.12% for graphite thickness and 0.24% for graphite length above which the values do not change [14]. When the results given in the table are examined, it is understood that the inoculant level of 0.06% and 0.12 is insufficient, and the inoculant level of 0.24 and 0.3 produces more suitable results in terms of length and thickness.…”

“…It was determined that the graphite length and thickness increased from thin section to thick section depending on the section thickness. It is known that the number of graphite increases as reported in many studies due to the increase in the amount of inoculant [14,[24][25][26][27].…”

“…In a different study, Colak [13] found that it is possible to reduce micro-porosity shrinkage with an improvement in fatigue resistance with optimization of the inoculation process and a decrease in the scattering band in fatigue test results. It is known that inoculants are also effective in the fluidity of cast irons [14]. The development of casting properties by processes such as inoculation, and alloying element additions during the production stages with cast iron is one of the commonly used applications.…”

Material suppliers typically recommend different additive amounts and applications for foundry practices. Therefore, even in the production of the same standard materials, different results may be obtained from various production processes on different foundry floors. In this study, the liquid metal prepared with the addition of different proportions of a FeSi-based inoculation, which is most commonly used in foundries in the production of a cast iron material with EN-GJL-250 lamellar graphite cast iron, was cast into sand molds prepared with a model designed to provide different solidification times. In this way, the optimization of the inoculation amounts on the casting structure for different solidification times was investigated. In addition, hardness values were determined depending on solidification time in varying amounts of inoculation additions. SolidCast casting simulation software was used to determine the casting model geometry and solidification time. In the scope of the study, sand casting, modeling, microstructure analysis, image analysis, microstructure analysis, and hardness tests techniques were used. When the results are examined, the required amount of inoculation for the optimal structure is optimized for the application procedure depending on the casting module and the solidification time.

“…The resulting shrinkage and expansion are affected by many parameters such as mold material, chemical composition, alloy overtemperature, inoculation quality, solidification time of casting (modulus), and casting speed. High carbon equivalent, high mold rigidity, high solidification time (high modulus), high inoculation quality (high nodularity), low casting temperature (low excess heat) and low casting to reach high dilation press and consequently lowly shrinkage [18][19][20].…”

The casting process involves filling a prepared mould cavity with molten metal, which takes the shape of the container. While the liquid metal takes the shape of the container it is in, the method is attractive, while the volumetric changes during the liquid-solid transformation reveal the importance of moulding design for the manufacture of solid parts. Especially in cast irons, moulds with the same design may produce different results depending on the changing casting and foundry conditions because the volumetric change that occurs during the solidification of ductile cast irons is affected by many parameters and develops differently than in steel and aluminium castings. This study used model wet and resin molding materials to create single and double-riser moulding and castings with different section thicknesses. The importance of the type of mold material used in castings and the number of feeders for the robust production of the cast part was evaluated using experimental and modeling techniques. When the results were examined, it was seen that the shrinkage risk was lower with resin mould than with green sand moulding. In addition, depending on the riser connection point, the importance of the riser neck has emerged.

“…Casting is an important forming method of parts or blanks, especially suitable for the production of complex shape parts, which is favored by production enterprises [1]. However, the casting or blanks produced by casting have defects such as shrinkage cavity, shrinkage porosity, and coarse structure, which lead to poor performance [2].…”

In order to reveal the effect of vibration solidification on microstructure and properties of gray cast iron in lost foam casting, Y-shaped HT100 gray cast iron was prepared by vibration lost foam casting, and the effect of amplitude on the microstructure and properties of gray cast iron was studied. The results showed that, with the increase in amplitude, the short and thin A-type flake graphite increases, and the austenite structure transforms from columnar to cellular. The hardness, tensile strength, and elongation of gray cast iron first increase and then decrease with the increase in amplitude. The appropriate amplitude in the process of Y-shaped HT100 gray cast iron by lost foam casting is 2 mm, while the tensile strength and elongation of gray cast iron are the highest, with the values of 147.51 MPa and 1.17%, respectively. The change of mechanical properties of gray cast iron is mainly determined by the morphology and distribution of austenite in gray cast iron and A-type flake graphite.
