Figure 5: This is a microphotograph (×40) of the surface of a fatigue fractured K wire. It shows the 3 characteristic areas of a fatigue fracture- initiation zone, “beachmarks” which are wave-like hills and troughs in the metal surface caused by arrests/starts of the crack propagation., and finally the area of sudden total fracture
