Pistons having a reinforcing member in the top piston ring groove position are well known. Such members are used to reduce mutual wear between the piston ring groove and the co-operating piston ring. This is designed for the first piston ring groove of the inner combustible engine. Because of the high similarity of the thermal expansion indexes of High Nickel Austenitic Cast lron and aluminum-silicon alloy, the use of this type of material will prevent the loose and/or detachment of the carrier from the aluminum piston body due to the fluctuation of thermal and mechanicalloads.
