Abstract
SUS430 ferritic stainless steel was subjected to equal channel angular extrusion (ECAE) at room temperature to a total strain of 2.3. It was shown that the sample processed by ECAE showed higher room temperature strength than the as-quenched sample. This is probably due to the heavily worked structure. On the other hand, annealing at 673 K and 773 K increased both strength and elongation of the ECAE processed sample. It is likely that higher strength is attributed to both the worked structure and fine substructures. It is also likely that higher elongation is attributed to the fine substractures. It is concluded that a combination of ECAE with annealing is available for improving the room temperature tensile properties of SUS430.
