Abstract

The effects of changing loading direction and strain aging on the tensile behavior of an aluminum-killed steel were investigated. Changes of the direction of tension led to large decreases of the uniform strain. However, the total strains to failure were little affected by prestrains up to about 7 pct, because of increased post uniform elongations. Aging at 150 °C after a tensile prestrain of 0.084 caused a large decrease in uniform strain in subsequent coaxial tension and significant increases in the uniform strains in noncoaxial tension. In all directions aging caused increases of yield strength and overall work-hardening rate but decreased total strains to failure.
