Indentation microhardness measurements have been made in a Fe-Cr-Mn alloy in which both f.c.c. psi and h.c.p. EGe phases were present. The martensitic epsilON phase was found to be only marginally harder than the austenite, in marked contrast with results for alloys containing significant amounts of carbon. The deformation modes in the epsilon phase were primary (0001) (1120) slip and secondary "1012" (1011) twinning. Significant shape anisotropy was exhibited by the indentations in this phase, but no definite hardness anisotropy could be detected, largely because of the relative insensitivity of pyramidal indenters to such effects.
