Formation of white etching cracks at manganese sulfide (MnS) inclusions in bearing steel due to hammering impact loading [PDF]

open access: yes, 2016
Wind turbine gearbox bearings (WTGBs) are failing prematurely, leading to increased operational costs of wind energy. Bearing failure by white structure flaking (WSF) and axial cracking may both be caused by the propagation of white etching cracks (WECs)

Influence of EP additive on tool wear in drilling of compacted graphite iron [PDF]

open access: yes, 2011
Compacted Graphite Iron (CGI) is a good option for the manufacturing of engine blocks, because of the possibilities to decrease the wall thickness and to operate at higher pressures. However, due to its greater tensile strength and hardness compared with

From atom scale to casting : A contemporary monograph on cast irons microstructure [PDF]

open access: yes, 2020
The origin of this monograph lies in a simple fact: there is a paradigm with cast irons, namely that these alloys have been produced and cast for thousands of years, yet they are among the most complicated alloys if we consider the formation of their ...
