Directional Recrystallisation In Mechanically Alloyed Metals
description Conventional recrystallisation heat treatments lead ultimately to a microstructure consisting of equiaxed grains. There is now an Industrial demand for the production of highly anisotropic grain microstructures by solid-state processing, rather than by the more usual directional solidification routes. The latter do not seems to be suitable for certain applications, including the fabrication of wafers with elongated grains. This research work deals with ·an investigation of directional recrystallisation, a solid-state process in which heavily deformed metallic samples are recrystallised to yield highly anisotropic, directional grain microstructures. The study includes mechanically alloyed ferritic stainless steels. Alloy U5ed wns dispersion strengthened, so thot the energy stored due to deformation can be very high. Directional recrystallisation was induced by using an experimental technique, in which deformed samples are in effect subjected to a moving heat source which leads 10 recrystallisation in temperature grndient. Concept of"Kinetic Strength" is used to measure the activation energy required for directional recrystallisation.
