Advances in Ductile Iron Research: new metallurgical understanding and its technological significance
(Polish Academy of Sciences, 2005-12)
The present work gives an updated view about important metallurgical concepts, concerning the influence that solidification structure, microsegregation, piece size and austenite characteristics, exert on final microstructure, ...
Influence of alloy element distributions on austempered ductile irons
(Maney Publishing, 2018-11)
The influence of alloy element distributions on austempered ductile iron microstructure and austempering treatment was analysed by a cellular automaton model that considers the ausferritic and martensitic transformations. ...
A cellular automaton-finite difference simulation of the ausferritic transformation in ductile iron
(Maney Publishing, 2018-09-22)
The development of the ausferritic transformation of a ductile iron was analysed using a novel cellular automaton-finite difference model, which considers geometrical details of the microstructure, nucleation of the new ...
Optimization of the rolling contact fatigue (RCF) performance of carbidic austempered ductile iron (CADI)
(Elsevier, 2020-03)
Austempered ductile iron (ADI) has a good combination of mechanical properties and castability allowing it to replace forged steels while offering lower costs. CADI is thought to improve ADI's abrasion resistance by the ...
Analysis of different approaches to model the austempering heat treatment of ductile irons
(John Wiley & Sons Inc, 2020-11)
Austempered ductile iron is a metallic alloy of technological interest. Currently, the part design is added by means of simulations performed by using different types of models. This work aims at comparing three models ...
Solidification, macrostructure and shrinkage formation of ductile and compacted irons
(American Foundry Society, 2020-04)
This manuscript summarizes recent investigation of the authors into the solidification and shrinkage defect formation of ductile and compacted graphite cast irons. The study makes use of the DAAS (direct austempering after ...

Quantification of the Fracture Surface Profiles Resulting from Different Loading Conditions on Ductile Irons
(Elsevier, 2015-01)
This study focuses on the characterization of the roughness of the fracture surfaces of spheroidal graphite irons of different matrix microstructures, generated under impact, bending and fatigue loading conditions. The ...
Damage Accumulation in Silica Glass Nanofibers
(American Chemical Society, 2018-07)
The origin of the brittle-to-ductile transition, experimentally observed in amorphous silica nanofibers as the sample size is reduced, is still debated. Here we investigate the issue by extensive molecular dynamics simulations ...
Microstrain measurements and damage analysis during tensile loading of intercritical austempered ductile iron
(Wiley Blackwell Publishing, Inc, 2020-08)
The study focuses on the measurement of microstrain and the assessment of damage during tensile loading of intercritical austempered ductile iron by using digital image correlation technique and in situ observations. The ...
