Abstract
The microstructure and elevated temperature compressive properties of a rapidly solidified NiAl–Cr(Nb)/Dy alloy fabricated by injection casting were investigated. The results reveal that the microstructure of the rapidly solidified alloy gets great refinement. The coarse Cr2Nb phase at the NiAl phase boundary in conventionally-cast alloy is replaced by NiAl/Cr2Nb lamellar eutectic microstructure in rapidly solidified alloy. In addition, in the rapidly solidified NiAl–Cr(Nb)/Dy alloy Cr7Ni3 rod-like particles precipitate in Cr2Nb phase, but no Ni5Dy particles precipitate. Compared with the conventionally-cast alloy, the rapidly solidified alloy owns more excellent elevated temperature compressive properties.
