Abstract

Un acero de alta resistencia comprende, durante el recocido intercrítico, aproximadamente 20-80% en volumen de ferrita y 20-80% de austenita, y en donde la temperatura Ms calculada para la fase de austenita durante el recocido intercrítico es <100°C. El acero de alta resistencia exhibe una elongación de tensión de por lo menos 20% y una resistencia a tensión última de por lo menos 880MPa. El acero de alta resistencia puede comprender 0.20-0.30% en peso de C, 3.0-5.0% en peso de Mn, con adiciones de Al y Si de modo que la temperatura intercrítica óptima está por encima de 700°C.
