Correlation of cavitation erosion resistance with indentation-derived properties for a NiTi alloy

An empirical relationship is established between the cavitation erosion resistance R-e of a Ni-rich NiTi alloy and the quantity W/delta (u), where W is the work of indentation and delta (u) is the unrecoverable plastic deformation. This relationship also provides evidence that both pseudoelasticity and pseudoplasticity contribute to cavitation erosion resistance. (C) 2001 Acta Materialia Inc. Published by Elsevier Science Ltd.
