For investigating time-dependent plastic deformation (i.e., creep) that is known to become more pronounced at small scale, nanoindentation creep test has been widely performed. Recently, some efforts have been made in applying spherical indenter to the research on creep properties, which can overcome some issues related to the use of a sharp indenter. However, in spherical indentation creep, systematic investigation on the effect of various experimental factors is limited by far. Therefore, in this study, the creep deformation of indium, a suitable material for studying room temperature creep due to its low melting temperature, was systematically explored through a series of spherical nanoindentation creep experiments with various indenter radii. From the relation between creep strain rate and maximum stress, the creep stress exponent and the activation volumes were estimated. The obtained results were analyzed in terms of the influences of experimental conditions such as tip radius and creep stress.
