Crystallography of Graphite Spheroids in Cast Iron

Mostrar todas las versiones(2)

To further understand graphite growth mechanisms in cast irons, this study focuses on the cristal structure of a graphite spheroid in the vicinity of its nucleus. A sample of a graphite spheroid from a commercial cast iron was characterized using transmission electron microscopy. The chemical compos...
