Özet:

 In this study; The feasibility of producing metal-metal composites from two different materials in liquid state while preserving their own structures was investigated. Production was made using the sand mold casting method using Spherical Graphite Cast Iron and Lamellar Graphite Cast Iron, both of which are in liquid form. Casting samples with 9 different parameters were produced, evaluated in terms of mechanical properties by metal microscopy, microstructural and tensile tests, and compared among themselves. It has been observed that material quality and casting parameters play a major role in a good liquid-liquid mixture, and this directly affects the structural and mechanical properties of the resulting composite. The structural effect of Lamellar Graphite Cast Iron on Spherical Graphite Cast Iron was clearly observed and it was observed that it caused the deterioration of the spherical graphite form in the microstructures. In addition, considering the temperature effect, the effects of the composite on microstructural and mechanical properties were examined by changing the casting temperature values with remote-connected runner designs and the results were compared with the intermediate form Vermicular Graphite Cast Iron material. The results also showed that the results may be lower than expected due to the high affinity or impact of the materials used on each other.

 Bu çalışmada; her ikisinin de kendi yapılarını koruyarak sıvı haldeki iki farklı malzemeden metal-metal kompozit üretiminin yapılabilirliği araştırılmıştır. Çalışmada her ikisi de sıvı halde olan Küresel Grafitli Dökme Demir KGDD ve Lamel Grafitli Dökme Demir LGDD kullanılarak kum kalıba döküm yöntemiyle üretimler yapılmıştır. Çalışmada 9 farklı parametrede döküm numuneleri üretilmiş, metal mikroskobu ile mikro yapısal ve çekme deneyleri ile mekanik özellikler açısında değerlendirilerek kendi aralarında kıyaslanmıştır. İyi bir sıvı-sıvı karışımında malzeme kalitesinin ve döküm parametrelerinin büyük bir rol oynadığı, bu durumun doğrudan ortaya çıkan kompozitin yapısal ve mekanik özelliklerini etkilediği gözlenmiştir. LGDD in KGDD e yapısal etkisi net bir şekilde gözlenmiş olup mikro yapılarda küresel grafit formunum bozulmasına neden olduğu görülmüştür. Ayrıca sıcaklık etkisi düşünülerek uzak bağlantılı yolluk tasarımları ile döküm sıcaklık değerlerinin değiştirilerek kompozitin mikro yapısal ve mekanik özelliklere etkileri incelenmiş ve sonuçlar ara form olan VGDD Vermiküler Grafitli Dökme Demir malzeme ile kıyaslanmıştır. Ayrıca sonuçlar, kullanılan malzemelerin birbirlerine ilgileri veya etkilerinin yüksek olması neticesinde sonuçların beklendiğinden daha düşük olabileceğini de göstermiştir.
