Optimization of conditions of metallothermic reduction of rare earth preconcenrtrates
Yılmaz, Serkan; Topkaya, Yavuz Ali; Department of Metallurgical and Materials Engineering (2007)
Rare earth ferrosilicon alloy is an important additive for ferrous metallurgy. It is mainly used to control the detrimental effects of sulfur in steel and to modify graphite structures in cast iron. The aim of this study was to optimize the conditions for the production of rare earth ferrosilicon alloy by metallothermic reduction process using a preconcentrate prepared from a bastnasite type of ore present in the Beylikahır-Eskişehir region of Turkey. In this study, the rare earth preconcentrate was reduced...
Production and development of aluminide coatings by chemical vapor deposition on nickel based superalloys for turbine engine applications
Ertürk, Umutcan; İmer, Muhsine Bilge; Department of Metallurgical and Materials Engineering (2017)
Diffusion coatings including aluminide coatings are utilized to improve the high temperature oxidation and corrosion resistance of turbine blades. Through the advancement in the aluminizing methods, higher purity and more homogeneously distributed coatings have been realized. The chemical vapor deposition (CVD) is the most advanced technique utilized for aluminizing process. The versatility of CVD provides a large possibility to control process variables such as temperature, pressure, gas flows and ratios, ...
Production of in situ aluminum-titanium diboride master alloy formed by slag-metal reaction
CHANGIZI, Ahmad; Kalkanlı, Ali; SEVINC, NACİ (Elsevier BV, 2011-01-12)
Al-TiB(2) master alloys have received much attention in recent years owing to their potential as efficient grain refiners for aluminum foundry alloys. In this study, the process of production of master alloys was investigated to develop a low cost method, namely, slag-metal reaction. This method can be used to fabricate Al-TiB2 master alloy in situ from the TiO(2)-H(3)BO(3)-Na(3)AlF(6) and Al system. Since the price of the raw materials is low and the technology is simple, the processing technique appears t...
Production of coal crusher hammer heads by bi-metal casting
Kırma, Turgut; Selçuk, Ekrem; Department of Metallurgical and Materials Engineering (2008)
In this study, by considering different mechanical properties such as wear resistance and toughness of two different metal alloys in design and production stages, bi-metal casting technique was used for producing composite material which will be a solution for the cracking and wear problem in coal crushing hammer heads. The failure analysis of the classical hammer heads which are made from Hadfield steels (austenitic steel) showed that there are crack formations through austenitic grains and also the phase ...
Development of high temperature creep resistant aluminium based sand cast magnesium alloys
Yalınız, Emrah; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2018)
The aim of this thesis is to develop alternative sand casting aluminum based magnesium alloys to substitute current sand castable helicopter transmission housing magnesium alloys such as ZE41A and EV31A. AZ91 magnesium alloy has also been preferred for helicopter transmission housing material. However, the lower creep resistance above 120 oC due to the presence of -(Mg17Al12) phase in the microstructure and showing varying mechanical properties in different section thicknesses limit the usage of AZ91 in th...
