Differences of the Fatigue Process of 0.45% C Steel Quenched and Tempered at Various Tempering Temperatures

Notch Sensitivity of the Fatigue Limit in High-Strength Steel

“…Table 2 lists the heat treatment conditions used. 14,15) Henceforth, the quenched and tempered specimen is called S45C(QT) and the annealed specimen is called S45C(A). The hardness, which is correlated with the fatigue limit, 3) was tested using a Vickers hardness tester.…”
