Production of ni3al-fe composite and investigation of mechanical properties
MetadataShow full item record
In intermetallics high resistance to creep and oxidation, high strenght, low density are desired properties. Sintering process was used in this study by adding different amounts of Fe powder to Ni-Al powder mixture. When the properties of the sample after sintering were examined 40% weight Fe added composition was found 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 40% Fe added composition had 5,82 gr/cm3 of density, 92,8 HB hardness values and displayed 221 MPa shear strength.
