Etude des mécanismes de solidification de pièces minces en fonte à graphite sphéroïdal obtenues par unprocessus de solidification pas à pas

Abstract : The aim of the present work is to identify the solidification mechanisms occurring during the casting of spheroidal graphite cast iron thin pieces by a step by step process. After a first observation of the state of the surface and the microstructure of the obtained pieces, a macroscopic description of the formation of the first shell along the mould is proposed. This model has been confirmed by simulation on organics and detailed with the quantification of the first shell growth speed and the suggestion of a more precise description of the solidification mechanisms
