Abstract

In this study, the effects of pouring temperature and pressure on structure and mechanical properties of Al - 10% Si alloys produced by green sand mold traditional gravity casting and counter gravity casting methods were investigated. The specimens were poured at 600, 640 and 690°C temperature under 100, 200, 250, 300 and 500 mmHg vacuum level. The results showed that improved mechanical properties were obtained by counter gravity casting process

Özet

Bu çalışmada, döküm sıcaklığı ve basıncının yaş kum kalıplar kullanılarak geleneksel yerçekimi (gravity casting) ve yerçekimine ters döküm (counter gravity casting) yöntemleri ile üretilen Al-% 10 Si alaşımının yapı ve mekanik özelliklerine etkileri araştırılmıştır. Alaşıma ait numuneler 600, 640 ve 690°C sıcaklıklarda 100, 200, 250, 300 ve 500 mmHg vakum seviyelerinde dökülmüştür. Elde edilen sonuçlar, yerçekimine ters döküm yöntemiyle üretilen parçaların geleneksel döküm yöntemiyle üretilen parçalarda daha üstün mekanik özelliklere sahip olduklarını göstermiştir.
