Abstract
uma chapa de aço tem uma composição química específica e tem uma estrutura representada por, por razão de área, ferrita: 5 a 60%, e bainita: 40 a 95%. quando uma região que é circundada por um contorno de grão que tem uma desorientação de 15° ou mais e tem um diâmetro circular equivalente de 0,3 µm ou mais for definida como um grão de cristal, a proporção de grãos de cristal, cada um tendo uma desorientação intragranular de 5 a 14° para todos os grãos de cristal é 20 a 100% por razão de área. uma densidade de precipitado de ti(c,n) e nb(c,n), cada um tendo, um diâmetro circular equivalente de 10 nm ou menos é 1010 precipitados/mm3 ou mais. uma razão (hvs/hvc) de uma dureza a 20 µm de profundidade a partir de uma su-perfície (hvs) para uma dureza do centro de uma espessura de chapa (hvc) é 0,85 ou mais.
