Abstract The tensile properties and fatigue behaviour of three solution-treated Fe-29 Mn-9 Al-C (wt%) alloys having various carbon contents leading to different volume fractions of austenite and ferrite phases were investigated. The carbon contents were 1.06%, 0.60% and 0.26%, respectively and the corresponding volume fractions of austenite were 100%, 90% and 45%, respectively. The alloy having 1.06% carbon possessed the best tensile properties but its fatigue behaviour was only comparable to the other two alloys with lower carbon contents. The alloy having 0.60% carbon possessed the lowest yield strength, but its fatigue life was slightly better than other two alloys. The alloy having 0.26% C possessed lowest elongation and medium strength, and its fatigue life was comparable to the other two alloys. Their tensile properties and fatigue behaviour were explained in terms of crack initiation, crack propagation, grain size, constituent arrangement and constituent fraction.
