Notes:
The microstructure evolution of Ti-Al peretectic system in transient stage and steady statein directional solidification was predicted via theoretical analysis. The solute distribution controlledby diffusion at and ahead the solid-liquid interface will determine whether the properitectic andperitectic phases can nucleate and grow ahead of the opposing solid phase. The formation of bandingstructure is possible in a certain composition range. At the steady state, a microstructure selection mapwas set up based on interface response function model. The microstructure of TiAl alloys withdifferent aluminum content was studied with Bridgman directional solidification method. Someevidence in the experiment has been found to support the theoretical prediction
