Elastic and plastic properties of gamma + laves phase in-situ composite alloys using nanoindentation techniques

In the present study, the local elastic and plastic properties of the y-TiAl and the Laves phases have been investigated in a series of y + Laves alloys using room-temperature compression, Vickers microhardness, and nanoindentation with an emphasis on elucidating the local property changes in y + Laves alloys deformed at room temperature. This study shows that nanoindentation can be used to provide useful information on plastic flow in multiphase intermetallic alloys.
