Investigation of Microstructure and Mechanical Properties of Vermicular Graphite Cast Iron by Using Thermal Analysis

Öz:

In this study, the microstructural and mechanical properties of Vermicular Graphitic Cast Iron (VGCI) material complying with EURO6 standard during engine block production were evaluated using thermal analysis. The production of this engine block was carried out in Erkunt Industry company by pot metallurgy method with a new production approach suitable for mass production. Thermal analysis technique was used as a production control tool during production. Samples taken from the produced block material were examined to analyze the microstructural and mechanical properties. The results of the study showed that the engine block produced conformed to the standards in terms of chemical composition, structure and mechanical properties. It was determined that the microstructure and mechanical properties can be ensured to comply with the targeted standards by using thermal analysis technique. Some foreign (European countries) approvals have been obtained for the produced material.

Vermiküler Grafitli Dökme Demir Malzeme Üretiminde Termal Analiz Kullanımı İle Üretilen Mikroyapı Ve Mekanik Özelliklerinin İncelenmesi

Öz:

Bu çalışmada; EURO6 standartına uygun Vermiküler Grafitli Dökme Demir (VGDD) malzemeden motor bloğu üretimi sırasında termal analiz kullanımı ile mikroyapı ve mekanik özelliklerin değerlendirilmesi yapılmıştır. Bu motor bloğunun üretimi Erkunt Sanayi firmasında seri imalata uygun yeni bir üretim yaklaşımla pota metalurjisi ile gerçekleştirilmiştir. Üretim sırasında termal analiz tekniği kullanılarak üretim kontrolü yapılmıştır. Üretilen blok malzemesi üzerinden alınan numunelerle mikro yapısal ve mekanik özellikler bakımından incelemeler yapılmıştır. İnceleme sonuçları; üretilen motor bloğunun kimyasal bileşim, yapı ve mekanik özellikler bakımından standarta uygun olduğunu göstermiştir. Yapı ve özelliklerin hedeflenen standartlara uygunluğu termal analiz kullanılarak sağlanabileceği tespit edilmiştir. Başarı ile üretilen malzeme için bir kısım yurt dışı (Avrupa ülkeleri) onayları da alınmıştır.
