Özet:

Metal matrix composites are widely preferred for engineering applications, especially aluminum is used as a matrix because of its unique mechanical properties in naval and aerospace industries. In the present paper, the creep behavior of an aluminum based metal matrix composite reinforced with TiB2 particles was studied for various over temperature range and stress levels. Aluminum 6061 was selected to be the metal matrix which has high strength to weight ratio and it is reinforced with TiB2 which has extremely thermal stability. TiB2 powder is added into the aluminum by varying the percentage of the powder by volume in order of 3,6 and 9 percent, respectively. The finite element analysis software package ANSYS® is used to obtain the creep behavior of the composite material. The influence of the over temperature rates, stress levels and volume of the TiB2 powders on the creep behavior were studied by using simple finite element model. Using such a simple composite model, remarkable savings in time and identifying the correct combination of the TiB2 powder can be obtained for creep conditions.
