WORK HARDENING IN FACE CENTERED SUBSTITUTIONAL ALLOYS

Abstract

A survey was made of all existing experimental data on the mechanical properties of single crystals of the face-centered cubic substitutional alloys. The free length distribution of dislocations was found to be independent of concentration. An important process for alloys is that by which a new slip band reduces the impurity stresses in its neighborhood. It was indicated that some process occurs during glide in face-centered cubic alloys which is able to erase the impurity stresses in the vicinity of the slip bands. This process may be the production, motion, and the settling down of vacancies and interstitials in such a way as to nullify impurity stresses. It was also suggested that source and impurity hardening play major roles in these alloys, whereas interaction hardening is unimportant for their mechanical properties.
