Abstract

Magnetic measurements were conducted on as received and strained samples taken from LC, HSLA, and ULC sheet steels. ASTM tensile samples were loaded in increments to predetermined strains and the Barkhaused signal measured. The Barkhausen signal, first moment increased as a load is applied. If the proportional limit, where stress in no longer directly proportional to strain is exceeded, there is a permanent change in the Barkhausen signal and the 0.2 % offset yeild stress. For samples modified in this manner, there is a linear relationship between the Barkhausen signal and the yield stress, elongation at the ultimate tensile stress, and the work harding coefficient.
