This study is on the production and testing of an aluminum metal matrix composite. Metal Matrix Composites can be produced in several different ways. In this study, an aluminum matrix composite is produced by direct addition of the reinforcement ceramic into the liquid metal. The ceramic reinforcement for this process was a mixture of TiB2 and Al2O3 which was produced by means of a thermite reaction of reactants Al, B2O3 and TiO2 all in powder form with their respective stoichiometric amounts. This ceramic mixture was ground to fine powder size and then added to liquid aluminum in small percentages. After casting and taking samples of unreinforced alloy and reinforced alloys, their tensile strength and hardness as material properties were measured and compared. Another issue is the wetting of ceramic particles by molten Aluminum. The aim of the experiments in general is to find a better way to produce a composite material with desired mechanical properties.

Effect of TiH2 particle size on foaming of aluminium
Kubilay, Ceylan; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2005)
A study is carried out on the production of aluminum foams via powder processing. The study deals mainly with the effect of TiH2 particle size on the process of foaming. Mainly two TiH2 particle sizes were used; namely 27,5 ?m and 8,5 ?m. Foaming experiments were carried out at temperatures between 675oC ا 840oC. The viscosity of the system is adjusted by controlled addition of Al2O3. The study shows that choice of foaming agent size is influential in the foaming process. With the use of fine foaming agent,...
Production and properties of in-situ aluminum titanum diboride composites formed by slag-metal reaction method
Changızı, Ahmad; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2005)
In this study, production and properties of titanium diboride particle reinforced aluminum matrix composite were investigated. TiB2 particles form in-situ through the reaction of TiO2 and H3BO3 and Na3AlF6 in aluminum melt. The results showed that the in-situ TiB2 particles formed were spherical in shape and had an average diameter of 1mm .Moreover, the distribution of TiB2 particles in the matrix were uniform. The ultimate tensile strength, yield strength, flexural stress and hardness were found to while r...
An investigation of the microstructural and mechanical properties of tri-calcium phosphates doped with aluminum and fluoride ions
Tahmasebifar, Aydin; Evis, Zafer; Department of Engineering Sciences (2011)
The aim of this study was to investigate the microstructure and mechanical properties of pure tricalcium phosphate (TCP) and tricalcium phosphates doped with aluminum (Al3+) and fluoride (F-) ions at different compositions. TCP was synthesized via precipitation method and sintered at 1100C for 1 and 5 h. It was observed that density and relative density of the sintered materials were decreased by extending the sintering time. Increased densities were achieved upon Al3+ and/or F- doping. For structural anal...
Synthesis and characterization of nickel based bulk amkorphous alloys
Arslan, Hülya; Mekhrabov, Amdulla O.; Department of Metallurgical and Materials Engineering (2004)
The aim of this study is to synthesize and characterize new bulk amorphous alloys in the Ni- based systems. Theoretical studies on the basis of semi-empirical rules and the electronic theory of alloys in pseudopotential approximation has been provided in order to predict the impurity elements that will lead to an increase in the glass forming ability of Ni-based alloy systems. Glass forming ability of ten different compositions of alloys of Ni-Nb, Ni-Fe, Ni-B, Ni-Hf and Ni-Cr was simulated by using FORTRAN ...
Spray rolling of rapidly solidified Al-FeV-Si alloy
Özyurda, Halit Akın; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2006)
In this study an experimental spray-rolling set-up is designed in order to produce rapidly solidified Al-Fe-V-Si flat product. Al-Fe-V-Si alloys produced by rapid solidification powder metallurgy (RSP/M) methods are mostly used in high temperature applications in aerospace and automotive industries. The RSP/M technique used is spray deposition, which is desirable because of the high cooling rates achieved, as a result fine silicide dispersoids and intermetallics are observed in the microstructure which are ...
