Effect of Surfaces on Mechanical Behavior of Metals

  • I. R. Kramer

Abstract

That the surface has a pronounced effect on the mechanical behavior of metals is well established. In spite of this, surface effects are often ignored with the result that many of the explanations concerning plastic-flow phenomena are inadequate. In the following discussion, it will be shown that surface effects exert a remarkable influence on creep and fatigue, as well as on the general plastic-flow characteristics of metals. The change in mechanical behavior has been studied on specimens with oxide and metallic films, both when subjected to a vacuum or inert-gas environment and when the surface was being removed during the deformation. The mechanical behavior was also found to be influenced by nonpolar solutions containing surface-active molecules.
