RISSensitivity of the Creep-Rupture Properties of Waspaloy Sheet to Sharp-Edged Notches in the Temperature Range 1000–1400 Deg F
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Time-dependent notch sensitivity of Waspaloy was observed at test temperatures from 1000 to 1300 deg F. Its occurrence in this range was dependent on the heat treatment. “Overaging” eliminated ...
Deformation Characteristics and Time-Dependent Notch Sensitivity of Udimet 700 at Intermediate Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Time-dependent notch sensitivity of Udimet 700 sheet, bar, and investment castings was observed between 1000 deg and 1400 deg F (538–760 deg C) but not at 1600 deg F (871 deg C). As was ...
The Influence of Simulated Service Exposure on the Rupture Strengths of Grade 11, Grade 22, and Type 304 Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High temperature exposures were carried out to simulate long-time service. Rupture curves for exposed Grade 11 and Grade 22 steels did not exhibit the instabilities characteristic of the unused ...
Extrapolation of Rupture Data for Type 304 (18Cr-10Ni), Grade 22 (2-1/4Cr-1Mo), and Grade 11 (1-1/4Cr-1/2Mo-3/4Si) Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Methods for determining 100,000 hr rupture strengths for setting Code stresses were evaluated critically. Using available data for Type 304, Grade 22, and Grade 11 steels, techniques were examined ...
The Dependence of the Notch Sensitivity of Waspaloy at 1000–1400 Deg F on the Gamma Prime Phase
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The morphology of the gamma prime phase was correlated with the mechanical behavior of Waspaloy sheet at 1000–1400 deg F. “Overaging” eliminated time-dependent edge-notch sensitivity and produced ...
Relationship of Mechanical Characteristics and Microstructural Features to the Time-Dependent Edge-Notch Sensitivity of Inconel 718 Sheet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Time-dependent notch sensitivity of Inconel 718 sheet was observed at 900 deg F to 1200 deg F (482–649 deg C). It occurred when edge-notched specimens were loaded below the yield strength and ...
Notch Sensitivity, Mechanical, and Microstructural Characteristics of TD-NiCr at Elevated Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tensile and creep-rupture tests were conducted for smooth and sharp edge-notched specimens of 0.015-in. (0.38 mm) thick TD-NiCr sheet at 1000 to 1800 deg F (538–982 deg C). The dislocation ...
Turbulent Wall Jets With Cylindrical Streamwise Surface Curvature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of surface curvature on the development of a two-dimensional wall jet is investigated experimentally by direct comparison between a wall jet flowing around the convex surface of a ...
Film Cooling With Normal Injection Into a Supersonic Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study of film cooling with subsonic gas injection into a mainstream with a Mach number of 2.90 is reported. Air, used as both the mainstream and secondary fluids, is injected ...
Small Scale Modeling of Vertical Surface Jets in Cross-Flow: Reynolds Number and Downwash Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Jet-crossflow experiments were performed in a water channel to determine the Reynolds number effects on the plume trajectory and entrainment coefficient. The purpose was to establish a lower ...
