BN İlavesinin Sıkıştırma Döküm Yöntemi ile Üretilen B4C/Al Hibrit Kompozitlerin Mekanik Özellikleri Üzerine Etkileri
Yürütülen çalışma kapsamında, bor nitrür (BN) ilavesinin bor karbür (B4C) ile güçlendirilmiş alüminyum (Al) kompozitlerinin mekanik özellikleri üzerindeki etkileri incelenmiştir. Ağırlıkça %5 B4C katkılı olarak hazırlanan alüminyum matriks kompozit malzemelere ağırlıkça %3, %5 ve %10 BN ilave edilerek ve 75 MPa basınç altında sıkıştırma döküm yöntemi ile döküm işlemi gerçekleştirilerek BN-B4C/Al hibrit kompozit malzeme üretilmiştir. Kontrol ve karşılaştırma amacıyla, BN ve B4C ilavesi olmaksızın alüminyumdan elde edilen numuneler kullanılmış; BN ve B4C ilavesinin üretilen malzemelerin yoğunlukları üzerine etkileri ve ortalama talaş uzunlukları incelenmiştir. BN katkısının mekanik özellikler üzerindeki etkisini belirlemek amacıyla, sertlik ölçümleri gerçekleştirilmiş; malzemelerin akma dayanımları, çekme dayanımları ve yüzde uzama miktarları çekme testi yardımıyla belirlenmiş ve karşılaştırılmıştır
