Abstract:MeV electron irradiation induced Solid-State Amorphization (SSA) in B2 intermetallic compounds was investigated by High Voltage Electron Microscopy (HVEM) and Molecular Dynamics (MD) simulation focusing on the relationship between the SSA tendency and martensite (MS) transformation. There is no relationship between the SSA tendency and the structure of compounds, however, an unique feature of SSA tendency was found in B2 intermetallic compounds; intermetallic compounds which show MS transformation has a tendency to exhibit SSA.
