Abstract: A composite tooth is described for working the ground or rocks. The tooth includes a ferrous alloy having a portion reinforced at least partially by an insert. The portion reinforced by the insert is configured to allow, after in-situ reaction, the obtention of an alternating macro-microstructure of millimetric areas concentrated with micrometric globular particles of titanium carbides separated by millimetric areas substantially free of micrometric globular particles of titanium carbides. The millimetric areas concentrated with micrometric globular particles of titanium carbides form a microstructure in which the micrometric interstices between the globular particles are also filled by the ferrous alloy. The macro-microstructure generated by the insert is at least 2 mm, preferably at least 3 mm from a distal surface of the tooth.
