It has been found from the analysis of X-ray diffraction and the observation of TEM that the metastable ordered orthorhombic martensite alpha(0) '' phase in the rapidly solidified Ti3Al-2Nb alloy transforms to various phases at different aging temperatures. When the alloy aged at temperature of 500 degrees C for 20 min, the alpha(0) '' phase decomposition into B2 and O phases is related to the stress in the alloy. When the aged temperature above 600 degrees C, the alpha(0) '' phase transforms to alpha(2) phase by both shearing and chemical ordering.
