Beschreibung
Zusammenfassung:	A tooth, which is a wear-resistant component, includes a core, and a body made of a first metal and disposed to enclose the core. The core includes a matrix made of a second metal, first hard particles dispersed in the matrix, and a hard structure extending from the corresponding first hard particle in a direction along the grain flow in the body, the hard structure being higher in hardness than the matrix.
