    1. 51. CHUNKY GRAPHITE IN SPHEROIDAL GRAPHITE IRON: REVIEW OF RECENT RESULTS AND DEFINITION OF A PREDICTING INDEX
      Jacques Lacaze (CIRIMAT, Université de Toulouse)
      21/06/2019, 10:30
      Highlight
      Graphite degeneracy in heavy-section spheroidal graphite cast irons is mostly associated with the formation of chunky graphite which consists of large eutectic cells with interconnected graphite strings. At low level, appearance of chunky graphite is limited to its non-aesthetic effect on machined surfaces, while at higher level it is detrimental for mechanical properties of the components....

    2. 12. CONTROL OF SOLIDIFICATION PATTERN OF CAST IRONS BY SIMULTANEOUS THERMALS AND CONTRACTION/EXPANSION ANALYSIS
      IULIAN RIPOSAN (POLITEHNICA University of Bucharest, ROMANIA)
      21/06/2019, 10:50
      Oral Presentation
      An experimental device conducts thermal analysis and volume change measurements in a single ceramic cup with cast iron quality as the variable. The recorded data are processed using specialized software. Experiments compare solidification patterns for white [WI], grey [GI] and ductile [DI] irons, to correlate the most important events between the cooling curves and contraction curves, to...

    3. 205. EFFECT OF Mn/S RELATIONSHIP IN PRECIPITATION SEQUENCE OF THE MnS IN A HYPOEUTECTIC GRAY IRON
      Manuel de Jesús Castro-Román (Cinvestav Saltillo)
      21/06/2019, 11:10
      Oral Presentation
      Deleterious effect of sulphur excess in gray iron is shortened by Mn addition. The suitable Mn addition according to sulphur in the metal is preformed according to the different addition rules available in open literature. With Mn addition is intended to avoid FeS formation by MnS precipitation that also prevents the undesirable effect of sulphur dissolved in the melt in the morphology of...

    4. 94. THREE-DIMENSIONAL STUDY OF NODULE CLUSTERING AND HETEROGENEOUS STRAIN LOCALIZATION FOR TAILORED MATERIAL PROPERTIES IN DUCTILE IRON
      Jakob Olofsson (Department of Materials and Manufacturing, School of Engineering, Jönköping University, Sweden)
      21/06/2019, 11:30
      Oral Presentation
      Tailored heterogeneous distributions of microstructural features enable extraordinary material performance in biological and physiological structures such as trees, the aortic arch, human teeth and dinosaur skulls. In ductile iron, a heterogeneous distribution in size and morphology of graphite nodules and variations of the fractions of ferrite and pearlite are created during...

    5. 123. CONTINUOUS CASTING OF HIGH CARBON STEEL: HOW DOES HARD COOLING INFLUENCE SOLIDIFICATION, MICRO- AND MACRO SEGREGATION?
      Anthony Nicholas Grundy (Thermo-Calc AB)
      21/06/2019, 11:50
      Oral Presentation
      One technology that is often employed in continuous casting of high-carbon steel billets to minimize centre- (or macro) segregation is hard secondary cooling. Investigations unanimously show, that hard cooling significantly reduces macro-segregation, but a mechanism for the reduced segregation is rarely given. In this paper the solidification of high carbon tire cord grade C80D cast as a...

    6. 11. ADVANCES IN MODELING OF STEEL SOLIDIFICATION WITH IDS
      Ville-Valtteri Visuri (Process Metallurgy Research Unit, University of Oulu)
      21/06/2019, 12:10
      Oral Presentation
      IDS (Inter-Dendritic Solidification) is a thermodynamic-kinetic software package that simulates phase changes, compound formation/dissolution, and solute distribution during solidification of steels as well as during their cooling/heating process after solidification. The software package also simulates solid-state phase transformations related to the austenite decomposition process at...
