•Randomly-dispersed grains of austenite increase the shear strength of a TRIP steel.•Clustered grains of austenite do not necessarily increase the shear strength.•Clustering of austenite facilitates plastic localization in the ferritic matrix. The influence of the spatial distribution of the austeni...
