中文摘要
The microstructure of Ti-24Al-14NB-3V intermetallic alloy with solution treated was investigated by trans mission electron microscopy (TEM) and selected area electron diffraction (SAD) in conjunction with X-ray energy dispersive spectroscopy (EDS) techniques. It shown that φ=50% ductile β0-phase and small amount of O phase,and α2 with the number of dislocations having c-component resulted in increasing slip system of the material, have contributed to a good combination of strength and ductility at room temperature. Owing to some reciprocal planes of similarity between α2 and O Phases, to distinguish both of two phases, a series of diffraction patterns obtained by tilting around one reciprocal direction of the phase are needed based on the systematic extinction and reciprocal planes sequences occurred in the diffraction patterns, if those patterns are not containing one of three reciprocal unit vectors, a*, b*, c* in terms of the crystal unit cell, a, b, c.
