Extrinsic Sources of Plastic Resistance

Metal from internal friction from velocity-stress curves [Pg.85]

It is quite clear from these data that intrinsic resistance to dislocation motion in these metals does not determine their indentation hardnesses. Internal friction measurements have yielded similar results. Therefore, extrinsic factors need to be considered. [Pg.85]

The commentary above refers only to pure, simple metals. It is not intended to apply to metallic compounds or to some transition metals. [Pg.85]

The structural materials used by engineers are not soft, but only deform plastically at large applied stresses. These result from a variety of extrinsic barriers to dislocation motion. Thus dislocations move freely between the barriers, but then stop until enough stress is applied to overcome the barriers. [Pg.85]
