Abstract

Bu
çalışmada sıcak presleme yöntemiyle AA 7075 Al alaşımı tozları ve B4C
parçacıkları ile fonksiyonel derecelendirilmiş malzemeler üretilmiştir. AA 7075
matris içerisine ağırlıkça %10 - %
60 arasında değişen oranlarda B4C ilave edilmiştir. Matris malzeme ve
parçacıklar 3 boyutlu karıştırıcıda karıştırılmıştır. Karışım tozlar değişen
sıcaklık (250, 350 ve 450oC) ve basınç (200, 300 ve 400)
değerlerinde preslenmiştir. Presleme işlemi sonrası 5 farklı geçiş bölgesine
sahip fonksiyonel derecelendirilmiş malzemeler üretilmiştir. Geçiş bölgelerinin
sertlik değişimini tespit için makro sertlik ölçümleri yapılmıştır. Üretilen
numuneler tel erozyon yöntemi ile kesilerek standart boyutlarda çapraz kırılma
test numuneleri elde edilmiştir.  En yüksek çapraz kırılma dayanımına 450oC
sıcaklıkta preslenen numunelerde ulaşılmıştır.

Investigation of Transverse Rupture Strength of AA7xxx Matrix Functional Graded Materials Reinforced B4C

Abstract

In this
work, functional graded materials were produced by hot pressing with AA7075
alloy powders and B4C particles. B4C particles between
10% and 60% by weight were added to the AA 7075 matrix. Matrix materials and
particles were mixed in a three dimensional mixer. The blend powders were
pressed at varying temperatures (250, 350 and 450°C) and pressures (200, 300
and 400 MPa). Functionally graded materials with 5 different transition zones
were produced after pressing. Macro hardness measurements were made to
determine the hardness change of the transition zones. The produced specimens
were cut using wire electrical discharge machining (WEDM) and transverse
rupture strength test specimens were obtained in standard sizes. The maximum
transverse rupture strength was reached at 450oC samples.
