Abstract
The microstructure of an oxide dispersion strengthened ferritic PM2000 steel with a strong initial (100) texture has been investigated after compression by dynamic plastic deformation (DPD) at room temperature to a strain of 2.1. Measurements using electron backscatter diffraction and transmission electron microscopy indicate that DPD along the (100) direction results in a lamellar-type microstructure, in which lamellae of the (100) orientation alternate with (111) lamellae. These lamellae have a common rotation (110) axis in the compression plane. The microstructure is quite heterogeneous, where regions containing very narrow lamellae (with (111) lamellae as narrow as 20-40 nm) and regions of comparatively broad lamellae are found.
