SOME ASPECTS OF ESTIMATION ACCURACY OF MEAN TRUE INTERLLAMELAR SPACING

, 2012
Lamellar microstructures are characterized by interlamellar spacings: random, apparent and true. The mean value of true interlamellar spacing can be estimated by measurements of apparent spacings, random spacings or by counting number of intersections ...

Computational modeling of the influence of the interlamellar spacing in pearlitic steel

, 2010
On the microscopic scale pearlite is a two-phase material with hard and brittle cementite lamellas that are embedded in a softer ferrite matrix. In each pearlite colony the cementite has a preferred direction whereas the crystallographic directions for ...

Microstructure Validation of Graph Theory Model-Derived Cooling Rates in the Wire Arc Additive Manufacturing of ER70S-6 Steel

Journal of Manufacturing and Materials Processing
Wire arc additive manufacturing (WAAM) enables high-rate fabrication of large metallic components, but spatial variations in thermal history can lead to microstructural heterogeneity that requires efficient process models to evaluate.

Directional growth of pearlite in iron--carbon eutectoid alloys. [Rate]

, 1977
Pearlite was transformed directionally by passing a zone of austenite through high purity Fe--C alloy bars of eutectoid composition. Using a small embedded thermocouple, the temperature gradient at both the austenitizing edge and the pearlite ...

Linking cooling conditions, pearlite characteristics, and mechanical properties in pearlitic ductile cast iron: experimental and simulation insights

Materials & Design
Microstructural features of ductile cast iron (DCI), including graphite morphology and the pearlitic matrix, are influenced by solidification and subsequent eutectoid transformation and can be effectively tailored through the cooling conditions.
