OVERLOAD EFFECT OF DIFFERENT MICROSTRUCTURES IN AN ULTRA-HIGH STRENGTH STEEL
|
Abstract:
In present paper the effects of overload on the fatigue crack initiation life ofmeta-bainite and martensite in steel 40CrMnSiMoV have been investigated.The results showthat compressive overload decreases the fatigue crack initiation life(N_i),while tensil
