Abstract

In this study, the porous samples were manufactured through self-propagating high-temperature synthesis (SHS) by adding 10 % Co and Cr to 50 % Ni – 50 % Al powders. 10 % Co and Cr added 50 % Ni – 50 % Al samples were mixed for 12 hours using a mixer with a rotational speed of 300 rpm and compacted under 100 MPa pressure. The obtained samples were then synthesized by moving them to an argon atmosphere and combusted with the aid of a tungsten electrode. The samples that were obtained after the combustion reaction were characterized in terms of their microstructure using SEM-BSE. The elemental and phase analysis were carried out using EDS and XRD, respectively. The EDS results showed that the dominant element was Ni and the presence of Co with Cr was less than that of Al. The XRD measurements suggested that the highest peak is belong to NiAl along with the lowest peaks presented by Ni3Al ve NiAl3. Cr added NiAl alloy was found to present the highest hardness value after performing hardness measurements. In addition, adding Co to NiAl intermetallic structure was also found to help increasing the hardness
