Abstract The phase constitution of a highly dense NiTi alloy prepared by combustion synthesis and treated at high temperature solution and aging was analyzed by X--ray diffraction and transmission electron microscopy (TEM). Two kinds of fine precipitates exist in the alloy besides Ti2Ni. One is the rhombohedral structure Ti11Ni14 (Ti3Ni4}) with a=0.67 nm and alpha=113.85 circ,  which has an orientation relationship with the matrix (B2 structure, a=0.302 nm): ＜111$＞Ti11Ni14∥＜111＞B2, {1－10＞Ti11Ni14∥{123}B2. Another one is an unreported metastable precipitate with a long range ordered structure caused by Ni at the positions of Ti in NiTi phase. Its lattice parameter (a=0.873 nm) is about 3 times of that of NiTi matrix and the molecular formula is Ti13Ni14.

Key words: NiTi combustion synthesis metastable precipitate≡
