FE-BASED COMPOSITION, PRECHAMBER COMPONENT AND METHOD FOR MANUFACTURING PRECHAMBER COMPONENT

摘要

A Fe-based ferro-aluminide intermetallic composition for use in a prechamber component of a piston engine, comprises at least 55 percent by weight of iron, 10 to 40 percent by weight of aluminum, and at least one of the substances selected from the group of B, C, Cr, Zr, Nb, Ti; the total amount of the substances selected from the group not exceeding 5 percent by weight. Al- so a method for manufacturing a prechamber compo- nent comprises a step of manufacturing a prechamber component or a component preform by a powder met- allurgical process from the said Fe-based composition.
