Abstract

Reaction synthesis, or combustion synthesis is a production technique in which the thermal activation energy required for the formation of a compound is sustained by exothermic reaction heat released in the reaction. Ti-Al alloys are promising materials for aircraft industry, and they could be produced by self-propagating high-temperature combustion synthesis. The purpose of the present study was to research the effect of high initial compacting pressures (420 MPa, 630 MPa and 850 MPa) on theporosity of $Ti_3Al$ which produced by volume combustion synthesis. Microstructure examinations were carried out with optical microscope (OM) and scanning electron microscope (SEM). For phase analyses, X-ray diffraction device(XRD) was used. A considerable decrease in porosity was obtained because of the increase in the initial compacting pressure.

Özet

Reaksiyon sentezi veya yanma sentezi, bir bileşiğin oluşumu için gerekli termal aktivasyon enerjisininreaksiyonda açığa çıkan ekzotermik reaksiyon ısısı ile sürdürüldüğü bir üretim tekniğidir. Ti-Al alaşımlarıuçak endüstrisi için gelecek vaat eden malzemelerdir ve kendiliğinden ilerleyen yüksek sıcaklık yanmasentezi ile üretilebilirler. Bu çalışmanın amacı, yüksek başlangıç presleme basınçlarının (420 MPa, 630MPa ve 850 MPa) hacimsel yanma sentezi ile üretilen $Ti_3Al$ bileşiğinin gözenekliliği üzerindeki etkisininincelenmesidir. Mikro yapı incelemeleri optik mikroskop (OM) ve taramalı elektron mikroskobu (SEM)ile yapılmıştır. Faz analizleri için ise X-ışınları kırınım cihazı (XRD) kullanılmıştır. Başlangıç preslemebasıncındaki artışa bağlı olarak gözeneklilikte önemli bir azalma olduğu sonucu elde edilmiştir.
