Abstract A Zr-rich phase, Ni_5Zr, with low melting point has been found in a Ni_3Alalloy doped with Zr (1.2at.-%). It will cause the incipient melt of the alloy after homogeniz-ing at 1300℃. This makes it difficult to homogenize the coarse casting structures completelyand limits further impovement of the properties.
