Abstract: A notch-sensitive forging was tested at 1300 F to measure the effect of machining practice and of limited variations in Kt and specimen size upon notch rupture life. Within the limits studied, ...

Abstract: The variable hot ductility of wholly austenitic Type 347 steel was found to be associated with the variable temperature of formation of a liquid phase (liquation temperature) in the microstructure ...

Abstract: The creep-rupture strength at 1200 deg F of Type 321 (“18 – 8 + Ti”) superheater tubing was shown in the preceding paper (ref. [1]) to be very low when made by the usual cold-working ...

Abstract: Medium-carbon steel piping, after about 200,000 hr of service, and carbon–0.5 molybdenum steel piping, after about 150,000 hr of service, have been evaluated to determine the effect of prolonged ...

Abstract: Extended research on creep rupture of notched specimens, conducted at the University of Michigan under Air Force sponsorship, is analyzed along with recent publications of others. The combined ...

Abstract: Specimens of 1.25 Cr–0.5 Mo steel which had been exposed for prolonged times at 1000 F under ASME Boiler and Pressure Vessel Code allowable stresses were rupture tested in order to evaluate ...

Abstract: Experimental heats of Type 304 steel, compositionally balanced to be wholly austenitic and thus simulate the material used to produce seamless superheater tubing, were prepared to determine the ...
