摘要

A cylinder head produced having partially reinforced cylinder heads, particularly of internal combustion engines, providing a preformed workpiece of a predetermined material composition, and casting on said workpiece a material capable of producing a bond with said predetermined material composition for forming a positive connection between said workpiece and said casting material, including a cast portion; and a preformed workpiece positively connected to said cast portion for reinforcing those parts of said cast portion which are highly stressed during use.
