Özet:

 


Nickel aluminide intermetallic compounds possess attractive properties that make them good candidates for high temperature structural applications. It is known that Ni3Al intermetallics are commonly used in various application fields with the addition of Cr, in particular as well as elements such as Ti, Co, Mo and Fe which are related to this group for improving properties thereof. Given this information, sintering process was used in this study by adding different amounts of Cr powder to Ni3Al powder mixture. When the properties of the sample after sintering were examined we were able to reveal the effects of Cr on Ni3Al and consider 3% Cr added compositions as the most suitable ratio in terms of mechanical properties. Analyses were conducted metallographically on the samples after sintering, the densities were calculated, hardness and shear strengths were determined. According to the data 3% Cr added composition had 5,23 gr/cm3 of density, 153,9 HB hardness values and displayed 307 MPa shear strength.
