..., in the “nanoindentation” technique, the indentations extend only to extremely shallow depths, often as low as nanometers. A hard indenter, usually an accurately ground diamond, is gradually pressed into the film, which is deformed first elastically and then plastically. Upon gradual removal of the load, the elastic...
