National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Material Physics of Deformation of AA5182 Under Hot Rolling Conditions.

DE2001763398

Publication Date	2000
Personal Author	Stout, M. G.; Beaudoin, A. J.
Page Count	6
Abstract	The forming process of hot rolling not only has obvious commercial importance but also is scientifically challenging to understand. Accurate characterization is difficult as material physics affecting plastic deformation change on the same time scale as that of the process itself. Recovery and recrystallization provide examples: the development of an annealed state may occur between rolling passes, with subsequent impact on upcoming rolling passes. We have used the constitutive response of the metal in interrupted loading experiments to ascertain whether recrystallization or recovery is an active mechanism as a function of deformation history, complimenting a study of Wells, et. al (1998).
