The automotive industry has used for many years exhaust gas catalytic supports based on heat resistant Fe-Cr-Al ferritic stainless steels. The Fe-Cr-Al alloys are usually cast and then rolled into a foil of desired thickness. Planar flow casting (PFC) represents a cheaper alternative route for production of thick ribbons of about 100 {micro}m directly from the melt. On the other hand, it is well established that a solidification rate as high as 10{sup 5} K s{sup {minus}1} can be reached by means of PFC. This rapid solidification rate determines better properties of the alloy associated with the fine and homogeneous microstructure developed. The aim of the present work is to study the relationship between the microstructure and the texture in ribbons of a Fe-25% Cr-5% Al alloy produced by PFC with a thickness ranging from 40--180 {micro}m. All composition are given in weight percent.
