TORSION FATIGUE AND RESISTANCE TO FATIGUE CRACKING OF THREE GRADES OF RAIL STEEL

ENDURANCE EN TORSION ET RESISTANCE A LA FISSURATION PAR FATIGUE DE TROIS NUANCES D'ACIERS A RAILS

The materials investigated were an 0.7C-0.95Mn-0.85Cr-0.77Si steel and two heat treated unalloyed steels with 0.79 and 0.60% C, with tensile strengths of 1065, 1260, and 1000 N/sq mm, respectively. Fracture toughness and fatigue crack formation and propagation are reported in terms of fracture mechanics. Woehler curves are given for torsion fatigue, and types of fracture are shown in fractographs.
