Abstract

CHAPA DE AÇO LAMINADA A FRIO E RECOZIDA COM EFEITO TWIP E PROCESSO DE OBTENÇçO. A matéria tratada refere-se aos aços laminados a frio e recozidos com efeito TWIP e ao seu processo de fabricação. Esse aço apresenta níveis de manganês entre 20% e 30%, de silício entre 1% e 3%, de alumínio entre 2% e 6%, de níquel entre 1% e 3%, de carbono entre 0,03% e 0,4% e de nitrogénio entre 0,001% e 0,008%, apresentando ductilidade devido à formação de macias durante o encruamento (efeito TWIP), podendo atingir alongamentos totais de até 95%, absorvendo enormes quantidades de energia. Além disso, tem menor densidade quando comparado aos aços carbono ou aços inoxidáveis.
