Fatigue Performance As Measured By Fatigue Strength Quenched and Tempered Steels
In a recent posting, a comparison of the fatigue properties for normalized steels (163-259 BHN) showed that the strain-life curves fell within a rather narrow band, especially in the long-life regime. It was pointed out that, under a circumstance such … Continue reading
