Özet


Bu çalışmada Küresel Grafitli Dökme Demirlerin (KGDD) mikro yapı ve mekanik özellikleri üzerine mekanik titreşimin etkileri incelenmiştir. Dökümler geleneksel yaş kum kalıpta yapılmıştır. Bu çalışmada, ferritik KGDD (GGG 40) malzeme kullanılmıştır. Çalışma sonuçları, titreşim uygulamasıyla KGDD malzemesinin mikro yapısı ve mekanik özelliklerinde değişimlerin meydana geldiğini göstermiştir. Sonuçlara bakıldığında, tane ve grafit küre boyutlarındaki küçülmeye bağlı olarak KGDD’in mekanik özellikleri gelişmiştir.
