An analysis is presented of the influence of microstructure on the mechanical properties of austenitic–martensitic high Ni steels containing Ti. On the basis of data taken from the literature as well as the results of the present investigation, it is concluded that the properties of these steels are primarily dependent on the volume fraction and morphology of reversed austenite. Since it has been found that for many applications of duplex alloys the fracture toughness is an important property, further investigation of the interdependence of this property and the morphology of austenite is required.
