The use of subgrains as imaged in the SEM from bulk specimens in the study of localized plasticity

Abstract

The ability to image subgrains in the SEM by channeling contrast affords the opportunity to study localized plasticity and quantify parameters not previously measurable. This paper examines some of the ways in which subgrain information may be used in the study of fatigue and creep phenomena. Fatigue crack tip stress range and the work required to form a fatigue crack may be estimated. An example of the measurement of subgrain misorientation due to creep is also given.
