Bu çalışmada birer adet ikili Al-9Si, üçlü Al-9Si-0,1Sr ve dörtlü Al-9Si-0,1Sr-0,6Mg alaşımı indüksiyonlu ergitme ocağında ergitme ve oda sıcaklığında tutulan kokil kalıba döküm yöntemi ile üretildi. Alaşımların yapısal ve mekanik özellikleri üretilen alaşım k…

Titanium and titanium alloys are suitable for a variety of applications, with their low density, high strength and high corrosion resistance. Despite strong mechanical and corrosive qualities, titanium use is restricted by its weak friction and wear characteri…

In this study, in an effort to develop polymer matrix composite materials, especially to be employed as workbench and kitchen bench usage, powdered waste porcelain was used as a filler to form satisfactory mechanical properties together with Salvadora persica …

Boron is a important element that can be used in many different fields such as the ceramic industry, fertilizers, insecticides, corrosion inhibitors and etc. Boric acid is a naturally occurring compound containing boron, oxygen and hydrogen (H3BO3) elements. I…

In this study, spruce wood’s boric acid and nano technological varnish different vacum/ diffusion in time impregnating with respect to ASTM 1413-76 standards and the changes on technological features are researched. Retention percent, bending strength, modulus…

Variable magnetic fields are widely used in energy production. Two methods can be applied to make the magnetic field variable. The first of these is to apply an alternating current to the insulated conductor on the outer surface of a core. The other is to rota…

Environmental problems, also defined as destruction of ecologic balance, are among the most significant problems of today’s world. Increasing mankind pressure on environment have made destructions of ecological balance evident. Such a case then emerged a nee…

Due to increase in heating rate of initial powders used for production of aluminium matrix composites in sintering furnace, both formation of undesired phases in content of the composite materials were prevented and production costs and duration were tried to …

Open channel flow is defined as fluid flow with a free surface open to the atmosphere. One of the main sources of resistance in open channel flow is the roughness of channel bed. The roughness of channel base and side walls must be considered seperately invest…

Bitumen polymer modification has a long history. However, most of the polymers currently used as additive in bitumen are not economically attractive. Thus, employing recycled materials in flexible highway instead of virgin ones has become a fundamental case …

Yenilikçi soğutma teknolojileri arasında yer alan ısı boruları, sahip olduğu özgün karakteristikler sebebiyle son yıllarda önemli bir araştırma alanı olarak ortaya çıkmaktadır. Isı boruları, taşınımla ısı geçişi ve sıvı-buhar faz değişimi ilkelerinden faydalan…

Friction stir spot welding (FSSW) method is prone to automation. In this way, by integrating the robot and automation systems have been easily developed. Thanks to the method, the effective overlapping joints can be obtained a short processing time. In the stu…

Analysis of faults in synchronous generators are so important to protect the generators and the power systems. In this paper, double line-to-ground fault analysis in unloaded synchronous generator is presented. Apart from the similar studies in the literature,…

In this study, Al-12Si ingot alloy was melted in an electric resistance furnace and then poured into metal moulds through traditional casting method. Optimum machining conditions is aimed to determine by investigating the effects of cutting parameters on surfa…

Ortodontik tedavi sırasında diş hareketini etkileyen önemli faktörlerden biri sürtünme kuvvetidir. Sürtünme kuvvetine etki eden faktörlere müdahale edilebilirse ortodontik tedavinin süresi ve başarısı ile ilgili olumlu tahminler yapmak mümkün olacaktır. Sürtün…

In this study, 0-12wt.% of Si3N4 or 0-30wt.% of SiC was added to the aluminum matrix by powder metallurgy method. Hence, the effect of reinforcement elements’s (SiC or Si3N4) amount on the mechanical properties was examined. Micro structures and crystal struct…

Stress corrosion is a dangerous type of corrosion occuring as a result of effective with corrosive environment and stress of sensitive a material. Many metallic material may be exposed to stress corrosion damage depending on operating conditions. In order to d…

Open-finance platforms can combine models from different vendors while still concentrating capital in the same trade. Shared data, objectives, and representations make decision diversity the relevant object, rather than diversity of model names. We call loadin…

The emergence of Open Finance is reshaping the global financial landscape by enabling greater data accessibility, interoperability, and innovation. However, this expanded connectivity introduces new layers of regulatory complexity, raising urgent concerns rega…

Kapadokya Bölgesi sınırları içerisinde yer alan Niğde ilinde, cami, müze, sanat galerisi, depo gibi farklı işlevlerle kullanılan ya da işlevsiz ve terk edilmiş durumda bulunan toplam 35 kilise ve şapel yapısı mevcuttur. Yapılan gözlemler, cami olarak işlevlend…
