Manufacture of Two-layers and Double-sided Iron Castings with Differential Structure and Properties [PDF]
, 2015 The paper proposes a new method of production of bilayer and double-sided castings with differentiated structure and properties using the technology of in-mold modification of the initial melt, smelted in a single melting furnace, which ensures formation

Hydrogen embrittlement of nodular cast iron [PDF]
Materials and Corrosion, 2020 AbstractFerritic nodular cast iron, intended for use as the material for inserts of canisters for long‐term geological disposal of spent nuclear fuel, was studied for hydrogen sensitivity. In the canisters, the insert provides the mechanical strength against external loads.

Difficulties in the Production of Ausferritic Nodular Cast Iron without Heat Treatment [PDF]
Archives of Foundry Engineering, 2023 The paper presents results of tests carried out on ausferrite carbide matrix alloyed ductile cast iron. The ausferrite was obtained via addition of Cu and Mo alloying elements. This eliminated heat treatment from the alloy production cycle.

Effect of carbon equivalent on graphite formation in heavy-section ductile iron parts [PDF]
, 2010 The influence of post-inoculation and of cerium and antimony additions on the solidification process and on the formation of chunky graphite in ductile iron heavy-section parts have been studied previously in the case of near-eutectic alloys. It appeared

Melt Stirring of Nodular Cast Iron [PDF]
Materials Science Forum, 2018 In this work the effects of stirring/vigorous shearing on matrix and graphite phase in nodular cast iron melt during solidification were studied. Several experiments were conducted for different cooling and stirring times. Samples were prepared and examinations of the microstructure were conducted and compared using Leica Optical Microscope and ...

Damage modelling in nodular cast iron [PDF]
Le Journal de Physique IV, 1993 The damage mechanism of two types of ductile cast iron have been studied by precise microscopical observations and careful chemical, morphological and mechanical characterizations. Two modes of damage are observed as a function of graphite morphology : the void growth at the pole of the graphite or the void growth by internal cracking.
