The formation of secondary phase in the non-equilibrium peritectic reaction was observed by precise transmission electron microscopy analysis. The microstructural evolution and phase selection regularities under different solidification velocities were constructed from the laser resolidification experiments. A new phenomenon involving two-phase coupled growth was firstly detected in the rapidly solidified Ti-Al peritectic alloy. The Ti-45Al-2Cr-2Nb alloy with fully lamellar structure ( a 2+ g ) was taken as an object to investigate the possible preparation of bulky metastable g phase materials based on both adjusting the competing nucleation relation and changing the growth kinetics condition.
