Effects of the normalizing time and temperature on the impact properties of ASTM A-516 grade 70 steel

  • 1. Instituto de Pesquisas Tecnologicas, Sao Paulo (Brazil)

Description

The influence of normalizing time and temperature, as well as the plate thickness, on the impact properties of ASTM A-516 grade 70 steel, is studied. Results show that different normalizing conditions may lead to equivalent microstructure with different impact properties. Normalizing conditions that cause low cooling rate in the critical zone exhibit banded microstructure with inferior impact properties. (Author)

Abstract (Portuguese)

Estuda-se a influencia da temperatura e tempo de normalizacao, alem da espessura da chapa a ser normalizada, nas propriedades de impacto do aco ASTM A-516 grau 70. Verificou-se que diferentes condicoes de normalizacao podem proporcionar microestruturas equivalentes, porem com diferentes propriedades de impacto. Determinadas condicoes de normalizacao, que conduzam a baixas velocidades de resfriamento na zona critica, fornecem estruturas bandeadas, com propriedades de impacto inferiores aquelas desejadas.
