Cavitation erosions of Fe-26Mn-6Si-7Cr-1Cu and Fe-20Mn-6Si-7Cr-1Cu shape memory alloys were investigated by using an ultrasonic vibratory apparatus. It is showed that both alloys have good cavitation erosion resistance. Fe-26Mn-6Si-7Cr-1Cu alloy is more resistant to cavitation erosion than Fe-20Mn-6Si-7Cr-1Cu alloy, which is mainly attributed to the higher strain-induced martensitic transformation energy and elastic deformation energy under a localized load.
