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 ...
Mechanical properties and electrochemical behavior of porous Ti-Nb biomaterials

Yılmaz, Eren; Gökçe, Azim; Fındık, Fehim; Hamit Ozkan Gulsoy; İyibilgin, Osman (ELSEVIER SCIENCE BV, 2018)

Ti-Nb-based alloys - with their superior mechanical properties and biocompatibility - are attractive biomaterials for orthopedic implants. By producing this alloys with a porous structure, it is possible to achieve mechanical ...
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 ...
Novel hydroxyapatite/graphene oxide/collagen bioactive composite coating on Ti16Nb alloys by electrodeposition

Yılmaz, Eren; Çakıroğlu, Bekir; Gökçe, Azim; Fındık, Fehim; H. Ozkan Gulsoy; Nagihan Gulsoy; Ozal Mutlu; Özacar, Mahmut (ELSEVIER SCIENCE BV, 2019)

A novel implant coating material containing graphene oxide (GO) and collagen (COL), and hydroxyapatite (HA) was fabricated with the aid of tannic acid by electrodeposition. The surface of Ti16Nb alloy was subjected to ...
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 ...
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 ...
