Rate-dependent indentation size effect on hardness and creep behavior of a titanium metallization film on alumina substrate

Nanoindentation tests were performed at room temperature to investigate the indentation size effect (ISE) and creep behavior of a titanium metallization film on alumina substrate. The ISE of hardness was examined at different loading strain rate (LSR). The effects of LSR and penetrating depth on nan...
