Development of Ultrafine Grained Austenitic Stainless

The development of ultrafine grained structures in 316L and 304-type austenitic stainless steels subjected to large strain cold working and subsequent annealing and their effect on mechanical properties were studied. The cold rolling was accompanied by a mechanical twinning and a partial martensitic transformation and resulted in the development of elongated austenite/ferrite grains with

DEVELOPMENT OF ULTRA- FINE GRAINED ALUMINIUM BY SEVERE

Whereas, in the “tops down” approach coarse-grained materials are refined into ultrafine -grained /nanostructured materials. Ultrafine grained (UFG) materials may be defined as polycrystalline materials having average grain size less than ~1µm. The grain sizes of UFG materials may lie within the sub-micrometer (100-1000 nm) range.

On the other hand, the microstructure development in the ultrafine grained iron is significantly different from that in the coarse grained iron; that is, dislocations are more densely introduced by the deformation and form no dislocation cell structure. However, the ultrafine grained iron never exhibits work hardening, and the proof stress is kept constant even after 40% cold rolling. This
