C. Juckum et al., EFFECT OF HOT REDUCTION RATIO AND SURFACE CONDITIONS ON THE FATIGUE-STRENGTH OF A SPRING STEEL, Revue de métallurgie, 90(1), 1993, pp. 107-114
The effect of hot working ratio (between 3.5 and 110) and surface cond
itions (as-rolled and after shot peening) on the fatigue strength of a
spring steel 50 CrV 4 has been investigated. The fatigue bending resu
lts show, on the one hand, no significant effect of the hot working ra
tio on fatigue strength and, on the other hand, the beneficial effect
of shot peening which improves the fatigue strength more than 70 %.
