Ordering Process in Heat-Resistant Titanium Alloys
The methods of diffraction electron microscopy have shown that long-range order sections are formed at aging temperatures up to 500°C in alloys high in aluminum,and the ordered phase is formed by nucleation and growth mechanism at 700℃ aging temperatures. Causes of changing the phase transformation mechanism have been discussed, and the relationship between the structure and properties of alloys, depending on the modes of processing has been analyzed. It is shown that toughness and ductility characteristics are improved due to the realization of homogeneous transformation mechanism, while the formation of particles by the heterogeneous mechanism results in the alloys embrittlement.
