Farklı bor kimyasalları ile borlanmış Inconel 625 alaşımının karakterizasyonu
(Pamukkale Üniversitesi Mühendislik Bilimleri Dergisi, 2017)Bu çalışmada, nikel bazlı süper alaşımlar içerisinde endüstride yaygın olarak kullanılan Inconel 625 alaşımı 3 farklı borlama tozu ile borlanmıştır. Kullanılan borlama tozları, %90 elementel nano bor tozu + %10 NaBF4 (NB), ... -
Friction stir welding of AZ31 magnesium alloys – A numerical and experimental study
(Brazilian Association of Computational Mechanics, 2017)In this paper, weldability of magnesium alloys by friction stir welding (FSW) method which is difficult to join by the fusion welding have been investigated experimentally and numerically. To this end, the connection of ... -
Quantized control settings based tuning of a heaving wave energy converter in irregular seas
(Taylor and Francis Inc., 2016)The increasing awareness of environmental issues attracts more attention on environmentally friendly energy sources. This leads to increasing research on effective use of renewable energy sources. Among them, wave energy ... -
Mechanical properties of friction stir welded St 37 and St 44 steel joints
(Carl Hanser Verlag, 2018)In this study, the weldability of lower strength St 37 grade steel plate with a higher strength steel plate (i. e., St 44) using the friction stir welding technique has been studied. St 37 grade steel sheets are widely ... -
Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2019)This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having ... -
Microstructural and Mechanical Properties of Friction Stir Welded Nickel-Aluminum Bronze (NAB) Alloy
(Springer, 2016)In this study, the applicability of friction stir welding to cast NAB alloy (i.e., C95800) with a thickness of 9 mm has been investigated. The joint performance was determined by conducting optical microscopy, microhardness ... -
Exergy analysis and performance improvement of a subcritical/supercritical organic Rankine cycle (ORC) for exhaust gas waste heat recovery in a biogas fuelled combined heat and power (CHP) engine through the use of regeneration
(MDPI, 2019)In the present study, a subcritical and supercritical regenerative organic Rankine cycle (rORC) was designed. The designed rORCs assist a combined heat and power (CHP) engine, the fuel of which is biogas produced from ... -

HHO enrichment of bio-diesohol fuel blends in a single cylinder diesel engine
(Elsevier Ltd, 2019)One of the primary aims of this experimental investigation is to examine hydroxy-gas enrichment effects on environmentally friendly but performance-reducing alternative fuels such as ethanol and biodiesel. Hydroxy gas is ... -
Effects of blanking speed on the shear surface of mild steel (St37)
(Polish Academy of Sciences, 2016)Blanking operation is widely used to cut sheet or plates by a shearing process between punch and die. The process of shearing and the conditions of the sheared surface are influenced by the punch, the die, the speed of ... -
Fatigue analysis of bolted flange joints of a rotary dryer
(Elsevier, 2016)This paper describes the fatigue failure of a rotary dryer in a chemical plant. The process conditions required the dryer to be rotated continuously at a speed of about two and half revolutions per minute. The shell structure ... -
