摘要
En 中文
MeV electron irradiation-induced structural changes in a C11(b)-Ti2Pd intermetallic compound were investigated by high-voltage electron microscopy to provide evidence for amorphous-phase formation in Ti-based (Ti > 50 at.%) intermetallic compounds. The Ti2Pd compound could not maintain its original structure against the MeV electrons, and a bct solid-solution phase was formed at 22, 103, and 298 K. At temperatures <= 103 K, halo rings appeared in the selected area diffraction patterns after the bct-phase formation under the irradiation. This fact suggests the occurrence of solid-state amorphization; however, an amorphous single phase could not be obtained in the Ti66.7Pd33.3 alloy. (c) 2013 Elsevier B.V. All rights reserved.
