摘要:Porous NiAl intermetallics with different porosities were successfully prepared by self-propagating high-temperature synthesis (SHS). Examination of the reaction process between Ni and Al as well as the oxidation properties of the resultant materials was carried out. The melting of Al is the precondition for the reaction between Ni and Al, the reaction process can be explained by dissolution-precipitation mechanism. Only minor weight gain (0.06%similar to 0.24%) and stable pore structures of porous materials after 200 hours oxidation at 650 C indicate that porous NiAl intermetallics have excellent oxidation resistance.
