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.

The Deformation Behavior of Non-Isoaxial Bicrystals of Fe-3% Si.

AD665583

Publication Date	1966
Personal Author	Hook, R. E.; Hirth, J. P.
Page Count	15
Abstract	The slip occurring in bicrystals of a high purity Fe-3% Si alloy subjected to small plastic strains by deformation in compression was investigated using etch pitting techniques. Five non-isoaxial cases were investigated. In each case one component crystal was oriented for <111>(011) type single slip and the second component was of a (001) or (111) axial orientation. Each contained a planar boundary lying parallel with the compression axis. The relationship between the impingement of slip bands on the grain boundary and the mutual crystallographic orientation of two component crystals was examined in terms of slip activation and compatibility of deformation. The consequences of the impingement of pure edge slip bands at a boundary were compared with those associated with pure screw slip bands. Under conditions of constant axial strain, yielding was found to depend on both the Schmid factors of the most favorable oriented slip systems and on the relative elastic moduli of the component crystals.
