title = "Analysis of carbides and inclusions in high speed tool steels",
abstract = "The fracture surfaces of fatigued specimens were investigated using scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDS). The aim was to quantify the distribution of cracked carbides and non-metallic inclusions on the fracture surfaces as well as on polished cross sections. The specimens were made of B{\"o}hler P/M steel grade 390s and 690s in both microclean and conventional grades.The results show that the content of non-metallic inclusions are higher in the conventional grades than in the microclean grades, but there were found to be no link between non-metallic inclusions and the crack initiation. Surprisingly, no differences were found between the carbide size distributions of the microclean and conventional grades. Also, the distribution of the fractured carbides was found to be the same regardless of steel type, manufacturing method or location on the specimen.",
