ժҪ The influence of aging treatment on precipitation behavior of �� phase in a new Ni-Co-Cr fastener superalloy, AEREX350, was investigated by means of optical microscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The precipitation behavior of �� phase with two kinds of morphologies in this material was found to be sensitive to the temperature and time of aging treatment. Time temperature transformation curves of these two �� phase were both achieved. Furthermore, diffraction patterns revealed the semi-coherent orientation relationship between �� phase and �� matrix. This approach may be used to optimize the microstructure of the alloy for excellent mechanical properties.
