Abstract



Bu çalışmada,
AA2024 veya AA6061 matrisli, B4C veya SiC partikül takviyeli olarak üretilen
kompozit malzemelerin mikroyapı, mekanik ve ısıl iletkenlik özelliklerine,
matris bileşimi ile basınç değerinin etkisi incelenmiştir. 48 μm ortalama
tane boyutuna sahip B4C tozları veya 37 μm ortalama tane boyutuna sahip SiC
tozları kullanılarak çelik borular içerisine 50x8 mm ölçülerinde preformlar
oluşturulmuştur. Basınçlı infiltrasyon tekniği kullanılarak 800 oC’de
7 veya 8 bar basınçlarda alüminyum matrisler preformlara infiltre edilmiştir.
Elde edilen kompozitlerin mikroyapı analizleri EDS donanımlı taramalı
elektron mikroskobu (SEM) kullanılarak incelenmiştir. Üretilen numunelerin
SEM görüntülerinde homojen bir mikro yapı dağılımı gözlemlenmiştir.
Numunelerin porozite analizi alkol içerisinde daldırmalı askı aparatlı hassas
terazi cihazı kullanılarak yapılmıştır. Basınç miktarı arttıkça, porozite
hacim oranlarında büyük ölçüde azama meydana gelmiştir. Matris elemanlarına
ayrı ayrı olarak infiltre edilen takviye elemanlarının matris elemanında
oluşturdukları yapısal farklılıklar, X-Işını difraksiyonu (XRD) ile
incelenmiştir.Üretilen kompozit malzemelerin basınç miktarının artması ile
sertlik dayanımlarında ve basma mukavemetlerinde artış meydana geldiği
gözlemlenmiştir. Mekanik özellikler açısından kıyaslamada takviye elemanları
açısından kıyaslama yapıldığındanda SiC takviyeli kompozit malzemelere göre
B4C takviyeli kompozit malzemelerin daha iyi mekanik özelliklere sahip olduğu
sonucuna ulaşılmıştır.

Effect Of Pressure On The Microstructure, Mechanical and Thermal Conductivity Properties Of Composite Materials with Matrix of AA2024 or AA6061 and Reinforced B4C or SiC Produced by Pressurized Infiltration Method

Abstract

In this study, the effect
of matrix composition and pressure value on the microstructure and mechanical
properties of composite materials produced by AA2024 and AA6061 matrix and 50%
B4C and SiC particle supplementation were investigated. Performs were formed by
using SiC powders with B4C powders having an average grain size of 48 μm and a
particle size of 37 μm. The prepared preforms were infiltrated with aluminum
matrices at 7 and 8 bar pressures using the pressure infiltration technique at
800
oC. The microstructure analysis of the composite materials was
carried out using EDS-equipped scanning electron microscope (SEM). A
homogeneous microstructure was observed at the SEM analysis of the obtained
samples. The porosity analysis was done by using the apparatus with the
suspension apparatus in the integrated alcohol. A decrease in the porosity
volume ratio was obtained with increasing pressure. It has been observed that
the increase in the pressure amount of the composite materials produced
increases the hardness strengths and compressive strengths. In addition, it is
observed that B4C reinforced composite materials have better mechanical
properties than SiC reinforced composite materials when the reinforcement
elements are compared.
