CHARACTERIZING FRACTURES BY ELECTRON FRACTOGRAPHY. PART IV. THE SLOW GROWTH AND RAPID PROPAGATION OF A CRACK THROUGH A NOTCHED TYPE 410 STAINLESS STEEL WIRE SPECIMEN,

Abstract

Electron microscopic examination of a fracture surface indicates that a basic difference in the fracture modes associated with slow crack growth and fast fracture can exist. The examination also shows that the ductile rupture dimples might be used to interpret the direction of crack growth in some instances, and that the shape of ductile rupture dimples is dependent upon the state of stress.
