Abstract: Tough-pitch copper was drawn and extruded in multi-pass operations to effective strains of 1.53 or area reductions of 80 percent. It appears that residual stresses and mean pressure did not ...

Abstract: When notch toughness is required in a forging for pressure vessel or piping application, many phases of the manufacturing process are involved. Some significant aspects including the role of ...

Abstract: In certain biaxial fatigue problems, the stress components can be represented as a superposition of mean components, and proportionally applied alternating components. Such representation is the ...

Abstract: During the last few years many utilities have been purchasing fossil fueled power plants designed to be used for initial or future cycling service. As more large nuclear units are placed in ...

Abstract: Annealed OFHC copper and SAE 1018 steel were reduced by multipass drawing from diameters of 25.4 mm (and smaller) to 11.8 mm. A comparison was made of the experimental draw stresses and those ...

Abstract: Oxygen-free copper was extruded in the form of short solid cylinders (25 mm dia × 25 mm long) with reductions of approximately 20 percent and then followed by a compression test restoring ...

Abstract: The variation of the viscosity of a lubricant as it passes through a concentrated contact with a Hertzian pressure profile is predicted by a simple model for the time dependent volume response ...
