Abstract

One of the major defects in the production of aluminum alloys by casting is hot tearing. In this study, hot tearing of 1050 and 5083 casting alloys with different properties were investigated and the design parameters and casting conditions caused hot tearing were determined. In addition, the effects of hot tearing on metallographic and mechanical properties were also investigated. In addition, the effects of hot tear on metal quality were investigated depending on the presence of porosities in the structure of the casting alloys by performing bifilm index measurements with the RPT method. Finally, natural frequency analyzes and vibration tests of casting alloys were carried out, and free vibration and buckling characteristics were investigated separately under different boundary conditions.

Özet

Alüminyum alaşımlarının döküm yoluyla üretilmesindeki önemli kusurlardan birisi sıcak yırtılmadır. Bu çalışmada, farklı özelliklere sahip 1050 ve 5083 döküm alaşımlarının sıcak yırtılmaları araştırılmış ve sıcak yırtılmaya neden olan tasarım parametreleri ile döküm koşulları belirlenmiştir. Ayrıca sıcak yırtılmanın metalografik ve mekanik özellikler üzerindeki etkileri de araştırılmıştır. Bununla birlikte, Vakum Altında Katılaşma Testi (VAKT) ile bifilm indeks ölçümleri gerçekleştirilerek sıcak yırtılmanın metal kalitesi üzerindeki etkileri, döküm alaşımlarının yapısındaki porozitelerin varlığına bağlı olarak incelenmiştir. Son olarak, döküm alaşımlarının doğal frekans analizleri ve titreşim testleri yapılmış, serbest titreşim ve burkulma karakteristikleri farklı sınır koşulları altında ayrı ayrı incelenmiştir.
