Abstract

The low temperature embrittling behavior in Fe-(17-33)%Mn-6%Si alloys has been investigated by Charpy impact tests and scanning electron microscopy. The embrittlement is attributed to the formation of epsilon martensite. If alpha prime martensite is formed during deformation, the formation of voids at the intersection of epsilon -plates is suppressed, resulting in ductile fracture when alpha prime martensite is ductile. An Fe-17%Mn-6%Si alloy which has ( gamma plus epsilon ) structure below 415 K retains high toughness down to about 150 K because of the strain-induced transformation to alpha prime martensite.
