Abstract

The effects of composition adjustment on the microstructures and properties of a first generation Ni-base single crystal superalloy DD416 were investigated. Four experimental alloys with adjusted compositions were directionally solidified and their microstructures were observed with scanning electronic microscope (SEM) and optical microscope (OM). The tensile and creep rupture properties were tested. The results showed that the volumes fraction of eutectic of the as cast alloys and heat treated alloys were obviously influenced by the slightly adjustment of composition, especially the change of Al and Ti contents. The tensile properties of the four experimental alloys were similar, but the creep rupture properties were affected by the adjustment of composition significantly.
