摘要：
The invention relates to a method for producing an internal combustion engine piston which is provided with at least one cooling channel (12) and at least one reinforced piston ring groove (14) consisting in producing a piston blank (1), in forming a groove (10) provided with a cooling channel (12) and an external ring (11) in said piston blank (1), in filling the cooling channel (12) with are movable material (2), in filling the external ring with a reinforcing material (3) in removing the removable material (2) and in finish-machining the piston. A piston made of aluminum alloy and produced according to the inventive method is also disclosed.
