- W77133918 abstract "Abstract : High Strength Low Alloy (HSLA) steels have been shown to posses high strength and toughness. Additionally, these steels can be welded without the normal preheating required by comparable HY-series steels. HSLA-100, 100 Ksi yield strength, contains increased amounts of copper, manganese and nickel over the currently certified HSLA-80. However, prior to use in Naval ship construction knowledge of the steels toughness behavior is necessary. Existing fracture mechanics models are not applicable to HSLA-100 because HSLA-100 has only 0.04% carbon and these models use carbides as the nucleation sites for cleavage fracture. This research is part of a program to investigate and model the micromechanics of deformation and fracture of HSLA-100. Tensile testing of hourglass shaped specimens was conducted at quasi-static strain rates. Individual tensile test temperatures ranged from 24 C to -196 C. True stress, corrected for necking, and true plastic strain were monitored throughout the tests. This allowed a comparison to be made between the plastic strain behavior of HSLA-100 steel and a traditional constitutive equation used to describe the stress-strain behavior of metals." @default.
