Characteristics of the transformations occurred within the intercritical interval of ductile iron
(Trans Tech Publications, 2010-12)
Austempered Ductile Iron (ADI) and fully ferritic ductile iron are frequently used to produce safety parts. A new kind of ductile iron (DI), usually referred to as “dual phase ADI” is currently under development. The matrix ...
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 ...
Numerical modeling of ductile crack extension in high pressure pipelines with longitudinal flaws
(ELSEVIER SCI LTD, 2011)
This study examines the applicability of a micromechanics approach based upon the computational cell methodology incorporating the Gurson-Tvergaard (GT) model and the CTOA criterion to describe ductile crack extension of ...
Rectificacion de aceros fragiles y ductiles: Parametros de entrada para obtener los mejores resultados
(2002-01-01)
In this work, the behavior of the steel surface grinding process with conventional grinding wheels was studied for various grinding conditions and a fixed dressing condition. The input parameters (wheel speed, workpiece ...
Behavior of austempered ductile iron (ADI) grinding using different MQL dilutions and CBN wheels with low and high friability
(Springer, 2020-04-27)
This work aimed to study the application of minimum quantity of lubricant (MQL) with the addition of water, respecting the proportions 1:0, 1:5, 1:10, and 1:20 oil-water, in the cylindrical grinding of austempered ductile ...
Performance of austempered ductile iron (ADI) grinding using diluted oil in MQL combined with wheel cleaning jet and different CBN grains friability
(Springer, 2020-03-01)
The large amount of heat generated during grinding is minimized using cutting fluid. However, they cause damage to human health and the environment and increase the cost of the process. Thus, reducing or replacing the use ...

Analysis of ductile cast iron solidification: numerical simulation and experimental validation
(TAYLOR & FRANCIS LTD, 2009)
This paper presents an experimental and numerical study of the solidification process of ductile cast iron under slightly hypereutectic conditions. The material thermo-microstructural behaviour is measured in tests performed ...

Ductile Shear Zones
(Elsevier, 2015)
Mylonite with a big delta mantled porphyroclast of K-feldspar in a matrix of quartz, mica and feldspar. Mylonite is derived from a porphyritic granite characterized by large K-feldspar phenocrysts (up to 20 cm long). ...
