Ductility analysis of RC beams considering the concrete confinement effect produced by the shear reinforcement: A numerical approach
In this paper, a simplified numerical approach to study the influence of the confinement effect provided by transversal reinforcement on the ductility behavior of RC beams in bending is proposed. A unidimensional FEM ...
Embrittlement of austempered ductile iron caused by contact with water and other liquids
(Maney Publishing, 2016-11-29)
Recent research has reported that austempered ductile irons (ADI) suffer a marked embrittlement when the material is tested in tension with its surface in contact with water. The objective of this investigation is to verify ...
Influence of nodule count, austenitising variables and matrix on ductile iron decarburisation
(Maney Publishing, 2010-12)
The surface decarburisation produced during the austenitising stage of ductile iron parts constitutes an issue that needs to be addressed in many manufacturing processes. This work examines the role that nodule count and ...
Characterization ofthe austemperability of partially austenitized ductile iron
(Elsevier Science Sa, 2013-05-14)
This study focuses on the characterization of the hardenability and the austemperability of partially austenitized ductile iron melts alloyed with small amounts of Cu, Ni and Mn. The hardenability was studied by using ...
Review on produccion processes and mechanical properties of dual phase austempered ductile iron
(American Foundry Society, 2012-01)
During the last few years, researchers have sought new ductile iron (DI) applications focusing on the development of mixed microstructures, such as ferritic-bainitic or ferritic-martensitic. These kinds of structures result ...
Challenge with the scatter in ductile to brittle transition fracture transition of polymers
(Budapest University of Technology and Economics, 2009-12)
Fracture of pearlitic ductile cast iron under different loading conditions
In this study, fracture surfaces of pearlitic ductile iron generated under impact, bending and fatigue tests were characterized and compared. The fracture mechanisms in each case were identified from the observation of SEM ...
Gating system design to cast thin wall ductile iron plates
(Taylor & Francis, 2009-05)
The present study describes the development of a horizontal and a vertical mould designed to produce thin ductile iron plates of 1·5–4 mm thickness. Both moulds used a non-pressurised configuration. The horizontal mould ...
Mechanism of the silicon influence on chilling tendency index and chill of ductile iron in thin wall castings
In the present work an analytical expression that combines the susceptibility of liquid cast iron to solidify according to the Fe-C-X metastable system (also known as the chilling tendency of cast iron), is proposed. A ...
