Surface integrity analysis of grinding on ductile iron

Autor: María Emilia Furno, Amadeo Daniel Sosa

Publikováno v: The International Journal of Advanced Manufacturing Technology. 110:2067-2078

Ductile iron (DI) is a widely used material and one of the most largely casts produced. Advances in the understanding of the characteristics and behavior of this material have led to the development of parts with dimensions and shapes close to the fi

Study of dimensional change of high-silicon ductile iron with ADI and Dual-Phase-ADI microstructures starting from different as-cast structures

Autor: Amadeo Daniel Sosa, María Dolores Echeverría, Ana Lucía Dai Pra, Alejandro Daniel Basso

Publikováno v: International Journal of Cast Metals Research. 31:144-152

In this work the percent dimensional change (DC%) and its dispersion in high silicon Ductile Iron with ADI and Dual-Phase-ADI structures obtained through heat treatment starting from different as-cast microstructures, was studied. Specimens were obta

Corrosion mechanisms in ADI parts

Autor: Amadeo Daniel Sosa, Caren Soledad Rosales, Silvia Noemi Simison, Roberto Enrique Boeri

Publikováno v: International Journal of Cast Metals Research. 29:106-111

The objective of this research is to study the influence of microstructure and grinding on the corrosion resistance of ADI in salt water. Immersion and electrochemical tests were performed on samples austempered at two different temperatures and grou

Machining and Heat Treatment Effects on Distortion and Residual Stresses in an Industrial Application of ADI

Autor: Amadeo Daniel Sosa, Osvaldo Julio Moncada, María Dolores Echeverría

Publikováno v: ISIJ International. 44:1195-1200

The machining and heat treatment, employed in the fabrication of ADI parts, produce distortions and residual stresses that can increase the scrap rate. In the present study, dimensional changes, shape distortions and residual stresses due to machinin

Surface reactivity of thin wall ferritic ductile iron. The effect of nodule count and grinding variables

Autor: Osvaldo Julio Moncada, Silvia Noemi Simison, María Dolores Echeverría, Amadeo Daniel Sosa

Publikováno v: Materials Letters. 62:100-102

Thin wall ductile iron (TWDI) castings constitute an attractive alternative to several applications in which the strength to weight ratio becomes a key design variable. In TWDI, the nodule count for a given chemical composition is highly dependent on

Influence of nodule count on residual stresses and distortion in thin wall ductile iron plates of different matrices

Autor: Nelida Mingolo, María Dolores Echeverría, Osvaldo Julio Moncada, Amadeo Daniel Sosa, Jorge Antonio Sikora

Surface characteristics of thin wall ductile iron (TWDI) parts, such as residual stresses, distortion and dimensional changes produced during casting and heat treatment, are relevant variables when it comes to production processes design. This work f
