Abstract (2. Language): 
In this study, boron carbide has been synthesized using boron and carbon elements. Ceramic-metallic composite material produced and tested from this material. The study established two phases. At the first stage, carbon and boron elements, which 4 different ratio, are produced in inert atmosphere with mechanochemical reaction. Products are sintered at 1550° C fort he formation of boron carbide crystals. At the second stage, 5 different rates of Al-B4C composites prepared by making a uniform ball mill, pressed into the plate 400 MPa pressure. After Al-B4C composites pressed at 600 ° C for 1 hour at atmospheric environment, their hardness measurements were carried out. At the end of the study, the sample which was sintered during 120 min in argon atmosphere, B/C ratio is 4/1 and 50% reinforced composite are chosen optimum parameters.

Abstract (Original Language): 
Bu çalışmada, bor ve karbon reaktiflerinden çıkılarak mekanokimyasal yöntemle bor karbür sentezlenmiş ve bu malzemeden stratejik öneme sahip seramik metalik kompozit malzeme üretilerek dayanımı test edilmiştir. Çalışma 2 aşamada gerçekleştirilmiştir. İlk aşamada, 4 farklı orandaki karbon ve bor elementlerinin inert atmosferde mekanokimyasal reaksiyonla oluşumu gerçekleştirilmiş, elde edilen ürünler 1550°C’de sinterlenerek bor karbür kristalleri oluşturulmuştur. İkinci aşamada, 5 farklı oranda hazırlanmış Al-B4C kompozitleri bilyalı değirmende öğütülerek 400 MPa basınçta plaka halinde preslenmiştir. Preslenen Al-B4C kompozitler 600°C’de atmosferik ortamda 1 saat süreyle sinterlendikten sonra sertlik ölçümleri yapılmıştır. Yapılan çalışmalar sonucunda optimum parametrelere sahip numune argon atmosferinde 120 dakika boyunca sinterlenerek hazırlanmış, B/C oranı 4/1 olan, %50 takviye katkılı kompozit numunesi olarak belirlenmiştir.
