A possible atomic model of the interface was suggested. Thus, approach was made to a mechanism on complex nucleation of α_2+γ two phases along α--Ti interface, and growth of α_2/γ/γ_t/α_2 or α_2/γ/α_2/γ as fundamental structural unit. Key words:  TiAl intermetallic compound      lamellar structure      rotation twinning analysis      interface      Received:  18 February 1992      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1992/V28/I2/14 1 Lipsitt H A, Shechtman D, Schafrik R E.
