RSA (Rapid Solidified Aluminum) is considered as an “aluminum superalloy” because very good strength values are obtained. The present sample contains 7.8% Ni; 4.3% Mo; 3.3% Zr; 2.6% each of Cu and Fe; 1% Mn and 0.7% Ti. The numerous intermetallic precipitations are barely distinguishable under the light optical microscope.
