The bainite transformation in a 30CrMnSi steel was studied by thin foil transmission electron microscopy. It was found that:(1) The lower bainite of twin rail mode or of side precipitation mode and the upper bainite of branch mode are present in the steel. The midribs occur in the lower bainite plates and the step-like fronts in the upper ones.
A Study of The Effect of Two-Stage Tempering on Mechanical Properties of Steel 30CrMnSi Using Analysis on Response Surface in Design of Experiment 2012 - 2012 Properties of 30CrMnSi steel was investigated and optimized by the mean of Response Surface methodology EFFECT OF THE HEAT TREATMENT ON THE steel grade is the most used steel. Due to the large section, blooms of the above steel exhibit after, heat treatment, inhomogeneous microstructures and mechanical properties continuously varying from the surface to the core of the bloom; impact notch strength and fracture toughness are everywhere quite low (at the 10 J and
Surface analysis techniques using electron microscopy for steel products are reviewed. The recent progress of scanning electron microscopy (SEM), transmission electron microscopy (TEM) and focused ion beam FIB are presented with some applications to steel surfaces, coating layers and corrosion products. Experimental Research on Failure Behavior of 35CrMnSi fragments using scanning electron microscopy (SEM), results show that when impacting velocity is higher than 0.574km/s, 35CrMnSi fragments present brittle dissociation transgranular fracture and also exist partial melting, adiabatic shear band, molten dimple and irregular particles size of 100m in the fracture surface.
Fractography is a method in failure analysis for studying the fracture surface of materials. Studying the characteristics of the fractured surface can help to determine the cause of failure in an engineered product.
