Mechanism of damage of ferritic ductile Iron, influence of matrix heterogeneity
(Trans Tech Publications, 2018-06)
Ferritic ductile cast iron (FDI) microstructure is composed by graphite nodules embedded in a ferritic matrix. It is usual to assume that the ferritic matrix is homogeneous. However, the experimental analysis shows impurities ...
An experimental study of steel fiber-reinforced high-strength concrete slender columns under cyclic loading
(2012-08-10)
Structural engineers usually limit the use of HSC columns to seismic active zones because of their britle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ...
Análisis estructural y modelado digital de afloramiento del basamento austral de la Cuenca Neuquina: evidencias de deformación progresiva vinculada a cizalla dúctilStructural and digital field model analysis of the southern basement of Neuquén Basin: progressive deformation linked to ductile shear
(Asociación Geológica Argentina, 2018-07)
El basamento del sur de la Cuenca Neuquina está integrado por metamorfitas paleozoicas de alto grado metamórfico. En el presente trabajo la fábrica tectónica de estas rocas fue analizada a través de estudios de campo en ...

Precipitation and dissolution of carbides in low alloy ductile iron plates of varied thickness
(Taylor & Francis, 2005-10-19)
The present work has investigated the feasibility of achieving carbide free microstructures in low alloy thin wall ductile iron (TWDI) after dissolution heat treatments. Studies were conducted using low alloy and unalloyed ...
Abrasion resistance of ductile iron austempered by the two-step process
(Elsevier Science SA, 2008-06)
The present work focuses in the study of the effect that a new two-step austempering heat treatment process, developed by Putatunda, has on the mechanical properties with emphasis on the response to the abrasive wear. A ...
Rolling contact fatigue behavior of dual-phase austempered ductile iron
(Elsevier Science Sa, 2019-01)
In this work the rolling contact fatigue (RCF) behavior of dual-phase austempered ductile iron (ADI) was studied and compared to that of conventional ADI. The effect of surface finishing (manual vs. automatic grinding) on ...
Experimental and numerical assessment of fracture toughness of dual-phase austempered ductile iron
(Wiley Blackwell Publishing, Inc, 2010-01)
The effects of the microstructure topology on the fracture toughness of dual-phase austempered ductile iron are studied in this paper by means of finite element modelling and experimental testing. To this end, specimens ...
Damaging micromechanisms in an as cast ferritic and a ferritized ductile cast iron
(Elsevier Science, 2017-03-15)
Mechanical behavior and damaging micromechanisms in Ductile Cast Irons (DCIs) are strongly effected by matrix microstructure (e.g., phases volume fraction, grains size and grain distribution) and graphite nodules morphology ...
Development and characterization of a new type of ductile iron with a novel multi-phase microstructure
(The Iron and Steel Institute of Japan, 2010-12)
Over the last few years two new types of Ductile Iron (DI) have been developed based on Austempered DI (ADI), called Dual Phase ADI and Carbidic ADI (CADI), respectively. In the light of the experience acquired when studying ...
