Which outcome occurred when meteoric iron was first forged in antiquity without controlled carbon content?

💡 Explanation

When meteoric iron was forged, rapid quenching resulted from uncontrolled hammering because iron-nickel alloys lack carbon, causing formation of brittle Widmanstätten structures and easy fracturing. Therefore brittle tools resulted, rather than superior alloys, disintegration, or slow carburization which all require controlled carbon addition and tempering.
