Source of abnormality in hypereutectoid steels

Dilatometric analysis of cementite dissolution in hypereutectoid steels containing Cr

Cementite dissolution in hypereutectoid steels containing Cr is analyzed using dilatometry combined with the consideration of the carbon content in the austenite. The results suggest that the austenite transformed from the mixture of ferrite and cementite can be approximated to have a carbon content corresponding to equilibrium with ferrite. The overall dissolution behavior of cementite is desc...

Mechanism of Abnormal Grain Boundary Ferrite Formation in Hypereutectoid Pearlitic Steels

Chromosomal Abnormality in Men with Impaired Spermatogenesis

Divorced Pearlite in Steels

Steels containing large carbon concentrations are used particularly when a large hardness is required, for example in the manufacture of components such as bearings. This, however, makes it difficult to shape or machine the alloys during the process of component manufacture unless they are first heat–treated into a softened condition. One method of achieving this economically is to generate a m...

Nanoprecipitates in Steels

The creep strength of ferritic steels can be substantially improved by the incorporation of a high number density of nano-scale dispersoids. Examples for such alloys are the oxide dispersion strengthened steels MA956, MA957, and PM2000. The dispersoids in these steels contain Y and Ti, or Y and Al. They can be as small as a few nanometers in size. Processing is traditionally carried out by mech...
