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, the mechanical properties of milled glass fiber reinforced polypropylene matrix composite materials produced by extrusion method were investigated. The grain sizes of the milled glass fiber powders were measured with an optical microscope and we…

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…

Dünyada enerji üretimi yapılan her yerde havayı kirleten maddeler atmosfere atılmaktadır. Özellikle yakma sistemlerinin baca ve egzozlarından çevreye yayılan bu kirleticiler insan sağlığını ve canlıların hayat şartlarını olumsuz yönde etkilemektedir. Yapılan b…

Hardox çelikler mükemmel aşınma direncine sahip, ultra yüksek mukavemetli, kayma ve darbe aşınmasına karşı dayanıklı martensitik çeliklerdir. Madencilik ve inşaat mühendisliği endüstrisinde ağır makineler ana uygulama alanıdır. Bu çalışmada, Hardox 400 çeliğ…

3D printing filling structures at prototyping and design stage are increasingly important issue for products with complicated shapes. The objective of the present study is to investigate 3D printing filling structures effect on mechanical properties and surfac…

Elektromanyetik alanların canlılar üzerindeki zararlı etkileri bugün için bilimsel çevreler tarafından en çok üzerinde durulan ve araştırmalar yapılan konulardan biridir. Elektrik enerjisi ile çalışan cihaz ve sistemler çevresine elektromanyetik enerji yaymakt…

Bu çalışmada, yarı-katı işlem yöntemi ile Al-SiC kompozit malzemelerin sabit yük altında aşınma davranışları incelenmiştir. A356 matrise, 4 farklı miktarda (%5, %10, %15 ve %20) SiC ilave edilmiştir. Titreşimli tip değirmende bilyesiz olarak (30 dakika) karışt…

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…

This paper presents the theoretical aspect of the creep behavior in materials, particularly in metallic materials. Different creep mechanisms were displayed. The main models developed to determine or extrapolate the rupture time of materials were presented. So…

Many well-known material structures, such as metals, ceramics or polymers, cannot meet all the technological demands. For this reason, there is ongoing research into new materials with advanced features. A composite material is consisting of at least two phase…

In this study, hybrid composite structures were manufactured by vacuum assisted resin transfer molding method using three different woven fabrics (jute, E-glass and carbon) as the reinforcing material and polyester resin as the matrix material. All composite…

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 …

Nowadays, as the population increase, various construction projects are made on soils which engineering properties are not suitable. Many stabilization methods are used in order to prevent deformations and loss of bearing capacity on such soils. However, most …

Numerous studies have been carried out in the field of material science for the development of lightweight materials with high wear resistance, high strength and good corrosion resistance. Aluminum and its alloys are one of the most important engineering mater…

Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…

Tüm dünyada evsel ve endüstriyel üretim işlemlerine bağlı olarak atıklar üretilmekte veya konut, köprü, yol ve benzeri yapıların tamiratı, tadilatı, yenilenmesi, yıkımı ve doğal afetler sonucu atık maddeler oluşmaktadır. Oluşan bu inşaat yıkıntı atıkları (İYA)…

Plasticity index is one of the most important parameters affecting the behavior of fine-grained soils under monotonic and dynamic loads. Besides, various correlations between plasticity index and strength properties of fine grained soils can be obtained depend…

Use of superplasticing chemical admixtures in concrete production is widespread all over the world and has become almost inevitable. Super-plasticizers (SPA), extend the setting time of concrete by adsorbing onto cement particles and provide concrete to preser…

This study was compiled from the results of various researches performed on using diethyl ether as a fuel or fuel additive in diesel engines. Three different techniques are used the reduction of the harmful exhaust emissions of diesel engines. The first tech…
