Abstract
The structure of the omega-phase which is formed by the quenching of Ti-14 wt%Mo alloy from 1223 K to 273 K was investigated at the atomic level using a high-resolution electron microscope (HREM). The HREM image were formed by using 15 diffracted waves including diffuse scattering due to the omega-phase. The focus of imaging was adjusted to aberration-free-focus (AFF) condition and the observed images were processed by a computer to reveal the structure of the omega-phase only. It was found that the omega-phase co-exists with an omega-like structure formed by vacancy clusters.Keywords
