In this work, superconducting and mechanical properties of BSCCO superconducting whiskers were studied in detail. Nanoindentation properties of the whiskers were analyzed by the Oliver and Pharr Method and Work of Indentation (WI) method. More accurate results using the WI method for both the hardness and the reduced modulus were obtained due to reduction of the pile-up error. The correct hardness and reduced modulus values were determined by considering the indentation size effect and the substrate (epoxy resin) effect. The modified composite hardness model and the composite reduced modulus model are the most suitable models to investigate the nanoindentation properties of the whiskers.
