Abstract  The texture of γ/γ'-αDS eutectic alloy during aging has been investigated by means of high resolution electron microscopy(HREM) and analytical transmission electron microscopy.It has been found that the products of phase transformation in γphase are different during aging at temperatures of 850 and 650℃.Stick-like orthorhombic Ni3Mo was precipitated inα fibers,the γ-N i3Al with lamella twin structure can also be found to coexist with Ni3Mo.EDAX analysis shows the solid solution of Ni,Al and small amount of V inαfibers.Correspondent:DAI Jiyan,(Institute of Metal Research,Chinese Acadamy of Sciences,Shenyang 110015)
Key words:  γ/γ'-αDS eutectic alloy      aging      phase transformation      precipitation
