Some Metallographic Observations Relating to the Fatigue of Metals

Abstract

Observations have been made on the microstructure of metals subjected to fatigue stresses. The changes observed include the appearance of deformation bands and crystallites in the original grains. A modification of the fatigue process occurs at high stresses where the rapid formation of crystallites causes a widespread disturbance of the grains.
