In the present paper, important results of our recent computer simulation of radiation-induced amorphization in the ordered compounds CuTi and Cu{sub 4}Ti{sub 3} are summarized. The energetic, structural, thermodynamic and mechanical responses of these intermetallics during chemical disordering, point-defect production and heating were simulated, using molecular dynamics and embedded-atom potentials. From the atomistic details obtained, the critical role of radiation-induced structural disorder in driving the crystalline-to-amorphous phase transformation is discussed. 25 refs., 4 figs.
