No satisfactory explanation of the fatigue mechanism of metals has yet been advanced. The generally accepted idea involving work-hardening and subsequent ‘brittle’ fracture cannot be substantiated by observation as being the only cause of fatigue failure. Observations I have made on pure aluminium and aluminium–½ per cent silver specimens have shown that the mechanisms of failure at high and low stresses are fundamentally different1.

A Slip-band Exudation Effect observed in Pure Aluminium
EARLIER work on the fatigue behaviour of aluminium − 4 per cent copper alloy had revealed that material was exuded from some of the active slip bands during the later stages of the fatigue test1.… Expand
Mechanisms and kinetics of the early fatigue damage in crystalline materials
Abstract The localization of the cyclic plastic strain and its effect on the hysteresis loop, on the surface relief evolution and on the internal dislocation structure of austenitic and ferritic… Expand
Slip band extrusion in fatigued close packed hexagonal metals
Abstract The surface topography produced in fatigued cadmium, zinc and magnesium polycrysatals is described: slip band extrusions occur in cadmium and magnesium but not in zinc. The distribution of… Expand
AFM evidence of surface relief formation and models of fatigue crack nucleation
Atomic force microscopy and high resolution scanning electron microscopy were used to find the true surface relief corresponding to persistent slip markings emerging from persistent slip bands on… Expand
A mechanism of fatigue failure
It was shown that when specimens of 2014-T6 aluminum, titanium (6 Al-4 V), and 4130 steel were fatigued, the strength of the surface layer increased. When the strength of this layer reached a… Expand
EFFECT OF ORIENTATION ON THE FATIGUE BEHAVIOR OF SURFACE GRAINS IN POLYCRYSTALLINE ALUMINUM
ABSTRACT The fatigue behavior of surface grains in aluminum is strongly dependent on their orientation. At small strain amplitudes the orientation which causes the least strain hardening of the grain… Expand
Corrosion-fatigue initiation processes in a maraging steel
AbstractThe fatigue-crack initiation behaviour of an 18% Ni maraging steel has been examined in both air and 3·5% sodium chloride solution. Cracks were found to initiate almost exclusively at iron… Expand
FATIGUE BEHAVIOUR OF ALPHA-TITANIUM AND ALPHA-TITANIUM–HYDROGEN ALLOYS
Abstract The fatigue behaviour of coarse grained α-titanium designated as I.M.I, titanium-115 has been examined at room temperature. The fatigue specimens were loaded in tension—compression about a… Expand
A model of extrusions and intrusions in fatigued metals I. Point-defect production and the growth of extrusions
Abstract Based on recent experimental observations a realistic model of the evolution of the surface profile of persistent slip bands (PSBs) in fatigued metals is proposed. An essential feature of… Expand
Fatigue of Metals
