Iacoviello, F., Classification of ductile cast iron specimens:a machine morphology of their graphite elements and useful characteristics, the features, learning approach, Frattura ed Integrità are extracted from the specimens images; these characteristics
2 Ductile cast iron as a material - EADIPS FGRE-Book Ductile iron pipe systems Chapter 2:Ductile cast iron as a material 2/4 05.2014 Fig. 2.5 shows spheroidal graphite nodules on the fracture surface of a duc - tile cast iron specimen.
In this paper an automatic procedure based on a machine learning approach is proposed to classify ductile cast iron specimens according to the American Society for Testing and Materials guidelines. The mechanical properties of a specimen are strongly influenced by the peculiar morphology of their graphite elements and useful characteristics
Different Types Of Cast Iron White cast iron, Grey cast Based on the alloying elements added, the variation in the solidification of the cast iron and heat treatment used, the microstructure of the cast iron can vary. Depending upon the application and the preferred mechanical properties, iron castings can be classified into the following.
Ductile Iron Data - Section 3 - Part 2The fatigue strength of Ductile Iron, like many other cast materials, is also influenced by both the cast section size and the specimen size. Both of these factors should be considered when extrapolating laboratory fatigue data to actual components, although the one-third safety factor may be sufficient to compensate for any degradation in

Fatigue strength of sharp V-notched specimens made of Dec 01, 2017 · The material under investigation is the EN-GJS-400 ductile cast iron with chunky and nodular graphite within a ferritic matrix. Table 1 summarizes its the chemical composition. Specimens used for both tensile and fatigue tests were taken from a cast cylinder (diameter 650 mm). In particular, specimens containing chunky graphite (CHG) were taken from the core of the workpiece, where such
Large scale axial fatigue testing of ductile cast iron for Sep 01, 2011 · Abstract. The present paper deals with axial fatigue testing of heavy section EN-GJS-400-18-LT ductile cast iron specimens with 120 mm × 140 mm cross section and also smaller cylindrical specimens with 21 mm diameter at room temperature and load ratio R = million cycles. Each heavy section specimen weights 380 kg. The specimens were cut from
