摘要	The microstructure and deformation behavior of high temperature tension of a directionally solidified (DS) NiAl-15Cr alloy have been investigated. The results reveal that the microstructure consists of dendritic beta-NiAl phase, interdendritic gamma/gamma' phase and transient layer gamma' phase. The alloy shows superplastic behavior when it is deformed under the conditions of temperature range of 1123-1373 K and initial strain rate range of 1.67 x 10(-4) - 1.67 x 10(-2) s(-1). The maximum elongation of 280% with m=0.22 is obtained at 1323 K and an initial strain rate of 8.35 x 10(-3) s(-1). The superplastic mechanism for the alloy is also discussed by the observation of the microstructures evolution during the superplastic deformation process.
