• Nanoindentation
• Creep behavior
• Strain rate sensitivity
• Power-law function

The creep process during the holding stage of nanoindentation test has been analyzed mathematically. It is shown analytically for the first time that the corresponding indentation depth-time relationship can be described by a power-law function, suggesting a direct application of nanoindentation for the determination of the strain rate sensitivity.
