“…In previous works 33,[45][46][47][48][49][50] it has been shown that eutectic carbides can act as initiation sites for cracks which are formed at carbide/matrix interface through interface decohesion. In the HSS inoculated with 0?3 vol.-%W, such microcracks initiate fracture that preferentially occurs by a debonding mechanism at the carbide/matrix interface (Fig.…”

Melt treatment methods that involve the addition of small amounts of surface-active or/and inoculating elements have permitted the development of improved high speed steels (HSSs) with greater carbide control. In this work, addition of powdered W and WC into the melt was used to improve the as cast microstructure of AISI M2 HSS and, as consequence, its properties after full heat treatment. Under the action of inoculants, there was a refinement of the primary grains of the matrix and a transition from a columnar dendritic mode of solidification (typically found in uninoculated AISI M2) to a predominantly equiaxed morphology in the inoculated steels. SEM and EDS confirmed that the inoculation favoured the formation of the M 6 C eutectic at the expense of the M 2 C and MC variants, which prevailed in the as cast microstructure of the uninoculated steel. The relationship between microstructure and the properties is discussed.

“…The flexural strength parameters thus represent an indirect method of toughness quantification. Other attempts have been made to quantify the tool steel toughness including deep U-shape notches having different notch root radii in flexural samples [25] and bend samples having different surface roughnesses [26] or the use of semi-empirical correlations [27] from other mechanical and/or microstructural data.…”

“…To cover the relevant load ratios from R = -1 to R = 0.5 in the cyclic fracture mechanics test, an 8-point bending setup was used. 14 Main focus was put on the load ratio R = -1 as pure alternating stress is the application-relevant load case during operation of the rotor shaft in a wind turbine.…”

In this paper, the effect of microstructure of a thick-walled rotor shaft for wind turbines on fracture toughness properties has been investigated. The relevant nodular cast iron grade EN-GJS-600-3 was processed using chill casting technology. Due to different solidification conditions over the wall thickness, heterogeneous microstructures were formed. To illustrate the influence of the microstructure gradient caused by chill casting technology, specimens were taken from different sample positions in the cross section of the casting component. A detailed metallographic analysis revealed essential differences in microstructure. The crack growth resistance under quasi-static loading conditions and the fatigue crack propagation under cyclic loading conditions were measured. The results of the static fracture mechanics investigations revealed that fracture toughness is strongly influenced by the microstructure of this pearlitic ductile iron grade. On the other hand, cyclic fracture mechanics analysis showed that the complex formation of the microstructure has only a minor effect on the fatigue threshold value, but microstructure has a significant effect on the stable crack growth. For the assumed load cases, it was shown that microstructure can be a dominant factor on the mechanical and fracture toughness properties.
