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 ...

Thin wall ductile iron castings are being used in the industry as a way to improve the strength to weight ratio of machine parts. The high cooling rate, suffered by thin wall parts during the solidification process, promotes ...

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 ...

This work studies the impact strength of thin wall ductile iron. The properties of thin wall plates cast on sand moulds of thickness ranging from 2 to 4mm, in which nodule counts ranging from 1 700 to 1 300 nod/mm2 are ...

Nitrogenase is an oxygen labile enzyme. Microaerobic conditions within the infected zone of nodules are maintained primarily by an oxygen diffusion barrier (ODB) located in the nodule cortex. Flexibility of the ODB is ...

Insects manifest effective immune responses that include both cellular and humoral components. Morphological and quantitative aspects of cellular and Immoral cooperation during nodule formation in Chrysomya megacephala ...
