Shear localization is often a failure mechanism in materials subjected to high strain rate loading. While the constitutive behavior of copper has been extensively studied, the influence of cold work, strain rate, and temperature on the microstructura

The fundamental processes controlling the high-temperature interaction of dislocations with precipitates in Al-alloys were investigated in real time by deforming specimens in situ in the transmission electron microscope at elevated temperature. The o

Publikováno v: Materials Science Forum. :93-98

Tensile specimens of an Al-4Mg-0.3Sc alloy in the peak-aged (8 hours at 553 K) and the over-aged (96 hours at 623 K) conditions, cold-rolled to a 70% reduction, exhibited dynamic continuous recrystallization during superplastic testing at 733 K and a

Reinforcement bars of microcomposite (MC) steel, composed of lath martensite and minor amounts of retained austenite, possess improved strength and corrosion characteristics over low-carbon (LC) steel rebar; however, their performance under shear loa
