Abstract
The precipitation and growth of αⳠphase from β phase in Ti-15Mn alloy after solid solution process was experimentally investigated. After heat treatment, the Ti-15Mn alloy consisted of αⳠand β phases. The αⳠand β phases were analyzed by X-ray diffraction, transmission electron microscopy and Fourier transforms. The results show a coherent relationship between αⳠphase and β-Ti matrix, which is (2 0 0)αⳠ// (1 1 0)β and (0 2 0)αⳠ// (1 1¯ 0)β. Through calculating one-dimensional and two-dimensional mismatch, it comes to a conclusion that the two-dimensional mismatch of αⳠphase and β-Ti matrix is 1.73%. It means that the αⳠphase can efficiently precipitate from β-Ti matrix. Furthermore, it grows along the resultant vectors direction which determined by one-dimensional mismatch energy.
