Abstract

Bu
çalışmada, saf alüminyum, ağırlıkça farklı bor karbür (B4C) veya
alümina (Al2O3) katkı oranlarında (ağırlıkça %0, 1, 3, 6,
9, 12, 15, 30) Al-B4C ve Al-Al2O3 kompozitler toz
metalürjisi yöntemiyle üretilmiştir. Bor karbür veya alümina katkı oranının
kompozitlerin gözenekliliğine, yoğunluğuna, Vickers sertliğine, basma
dayanımına ve mikroyapısına olan etkisi incelenmiştir. Test sonuçlarına göre; en
yüksek deneysel yoğunluk, Vickers sertliği ve basma dayanımı Al-%30B4C
(deneysel yoğunluk: 2.7 g/cm3, bağıl yoğunluk: %96.7, sertlik: 75
HV, basma dayanımı: 178 MPa) ve Al-%30Al2O3 (deneysel
yoğunluk: 2.56 g/cm3, bağıl yoğunluk: %87.7, sertlik: 52 HV, basma
dayanımı: 162 MPa) kompozit yapıda elde edilmiştir. S
af alüminyuma kıyasla Al-%30Al2O3
kompozitin sertliği %73.3 ve basma dayanımı %80; saf alüminyuma kıyasla Al-%30B4C
kompozitin sertliği %150 ve basma dayanımı %98 oranında artmıştır.
Sonuç olarak, Al-B4C
kompozitlerin Al-Al2O3 kompozitlere göre hem
mikroyapılarının daha yoğun olduğu hem de mekanik özelliklerinin daha üstün
olduğu tespit edilmiştir.

Abstract

In
this study, pure Al and Al-B4C, Al-Al2O3
composites with various boron carbide (B4C) or alumina (Al2O3)
content (1
, 3,
6, 9, 12, 15, 30wt.%)
were fabricated by powder metallurgy method. The
effect of the boron carbide or alumina reinforcement ratio on the porosity,
density, Vickers hardness, compressive strength and microstructure of the
composites was investigated. According to the test results, the highest
experimental density, Vickers hardness, and compressive strength were obtained
at Al-30%B4C (experimental density: 2.7 g/cm3, relative
density: 96.7%, hardness: 75 HV, compressive strength: 178 MPa) and Al-30%Al2O3
(experimental density: 2.56 g/cm3, relative density: 87.7%, hardness:
52 HV, compressive strength: 162 MPa) composite structure. The hardness and
compressive strength of Al-30%Al2O3 were increased by
73.3% and 80% compared to pure aluminum. On the other hand, the hardness and
compressive strength of Al-30%B4C enhanced by 150% and 98% compared
to pure aluminum.  As a result, it has
been determined that Al-B4C composites have a denser microstructure
and higher mechanical properties than Al-Al2O3
composites.
