Effects of processing parameters on the production of beta-SiAlON powder from kaolinite

Tatlı, Zafer; Demir, Adem; Yılmaz, Ramazan; Çalışkan, Fatih; Kurt, Ali Osman (ELSEVIER SCI LTD, 2007)

In this study, the production of beta'-Si6-zAlzOzN8-z (z = 3) powders by the carbothermal reduction and nitridation of kaolinite (Al2O3 center dot 2SiO(2)center dot 2H(2)O) of Turkish origin (Can-Canakkale) was investigated ...
Effects of Sintering Temperature and Time on the Properties of Al-Cu PM Alloy

Gökçe, Azim; Fındık, Fehim; Kurt, Ali Osman (CARL HANSER VERLAG, 2017)

Aluminium-based powder metallurgy (PM) alloys have a number of advantages over cast and wrought aluminium alloys. These PM alloys can be produced using either prealloyed or elemental premixes, with the latter offering a ...
Effects of TiO2 on the mechanical properties of the Al2O3-TiO2 plasma sprayed coating

Yılmaz, Ramazan; Kurt, Ali Osman; Demir, Adem; Tatlı, Zafer (ELSEVIER SCI LTD, 2007)

Plasma sprayed ceramic coatings are successfully used in many industrial applications, where high wear and corrosion resistance with thermal insulation are required. In this study, various types of Al2O3-TiO2 plasma sprayed ...
Experimental and numerical studies of metal powders pressed by uniaxial floating die: Case copper and bronze

Yıldız, Aysel; Kurt, Ali Osman; Yıldız, Abdullah (REDAKCIA KOVOVE MATERIALY, 2004)

The results obtained from experimental, statistical (best fit) and numerical studies were found to be in good agreement, and showed that a hyperbolic relationship existed between the density and pressure.
From earth minerals to nitrides

Kurt, Ali Osman; Canikoğlu, Nuray; Toplan, Hüseyin Özkan (2007)
Microstructural examination and properties of premixed Al-Cu-Mg powder metallurgy alloy

Gökçe, Azim; Fındık, Fehim; Kurt, Ali Osman (ELSEVIER SCIENCE INC, 2011)

This paper reports the experimental findings on the development of the premixed elemental Al5Cu and Al5Cu0.5Mg powder metallurgy alloys. Aluminum powder was mixed with copper and magnesium powders in a macro- and a micro-level ...
Production of Sinterable Si3N4 from SiO2-Li2O-Y2O3 Mixture

Canikoğlu, Nuray; Yıldız, Kenan; Toplan, Hüseyin Özkan; Kurt, Ali Osman (TAYLOR & FRANCIS INC, 2012)

In this study, fine grained SiO2 was exposed to CRN, and then Si3N4 ceramic powders were produced. Initially, 5wt% Li2O-5 wt% Y2O3 (based on the final product) and carbon black were added to SiO2, and then powder samples ...
Sintering and aging behaviours of Al4CuXMg PM alloy

Gökçe, Azim; Fındık, Fehim; Kurt, Ali Osman (TAYLOR & FRANCIS LTD, 2016)

Sintering and aging behaviours of Al-Cu-Mg powder metallurgy (PM) alloy produced from elemental powders were examined. After evaluating results from thermal analysis, tests were carried out on Al-4Cu alloys with magnesium ...
Synthesizing high alpha-phase Si3N4 powders containing sintering additives

Canikoğlu, Nuray; Kurt, Ali Osman; Toplan, Hüseyin Özkan (ELSEVIER SCI LTD, 2009)

Fine grain alpha-phase silicon nitride (Si3N4) ceramic powders were produced via carbothermic reduction of colloidal SiO2, which contained pre-mixed additives of sintering aids primarily consisting of oxides such as MgO ...
The effect of Mg(NO3)(2) addition on the formation of AlN nanowire by direct nitridation

Kurtuldu, Fatih; Gökçe, Azim; Kurt, Ali Osman (SPRINGER, 2018)

In this study AlN nanowire was produced via direct nitridation (DN) method. In order to investigate the effect of nitridation on the formation of nanowire, elemental aluminum powder and ammonium chloride (NH4Cl) mixture ...
