Patent ID: 8034205

Claim:
A method for manufacturing a multimaterial component or structure, said method comprising the following steps: forming a body of a basic material by casting, said body comprising at least one attachment point for at least one piece of wear resistant iron based material; forming the at least one piece of wear resistant iron based material by casting or power metallurgical method; and joining the at least one piece of wear resistant iron based material to the at least one attachment point of the body formed of the basic material at a temperature (° C.) which is not more than 80% of the lowest melting point temperature (° C.) of the materials to be joined to form a multimaterial component or structure; wherein the multimaterial component or structure satisfies the following formula: A/ 5 +B/ 10>6 where A represents: Σ (volumetric fraction of the at least one piece of wear resistant iron based material relative to the entire volume of the multimaterial component or structure), and B represents the weighted average of the HRC hardness of the at least one piece of wear resistant iron based material, where the weighted average is calculated with respect to the volumetric fraction of the at least one piece of wear resistant iron based material in the total volume of wear resistant iron based material.
