摘      要：The recrystallization behaviour of cold drawn MP159 alloy was investigated by optical and TEM examinations. It is found that the platelet epsilon phase in the MP alloy inhibits the recrystallization, and this effect makes the MP159 alloy with high recrystallization temperature of about 920 degrees C. This inhibition mainly comes from the increasing of the interfacial energy, which results from the change of the coherent interfaces of (0001)(hcp)//(111)(fcc) into the incoherent interfaces when the recrystallizing grain fronts bypass the platelet epsilon martensite. The increasing of the interfacial energy also causes the dissolution of a few segments on the epsilon martensite platelets, which decreases the strength of the MP alloy.
