Abstract

Indentation-induced phase transformation processes were studied by in situ Raman imaging of the deformed contact region of silicon, employing a Raman spectroscopy-enhanced instrumented indentation technique. This is, to our knowledge, the first sequence of Raman images documenting the evolution of the strain fields and changes in the phase distributions of a material while conducting an indentation experiment.
