Book Description
A survey was made of portions of the Chromium-cobalt-nickel-molybdenum quaternary system at 1200 degrees C by means of microscopic and x-ray diffraction studies. Since the face-centered cubic (alpha) solid solutions form the matrix of almost all practically useful high-temperature alloys, the solid solubility limits of the quaternary alpha phase were determined up to 20 percent molybdenum. The component cobalt-nickel-molybdenum, chromium-cobalt-molybdenum, and chromium-nickel-molybdenum ternary systems were also studied. The survey of these systems was confined to the determination of the boundaries of the face-centered cubic (alpha) solid solutions and of the phases coexisting with alpha at 1200 degrees C.

Experimental Investigation of a 90 Degree Cascade Diffusing Bend with an Area Ratio of 1.45:1 and with Several Inlet Boundary Layers

Book Description
An experimental investigation was conducted in order to determine the performance of a 90 degree cascade diffusing bend with an area ratio of 1.45:1 and a 19-inch square inlet with several inlet-boundary-layer shapes and thicknesses. The maximum mean inlet Mach number was 0.41 and the corresponding airfoil Reynolds number was 950,000. The experimental results seem to indicate that, when the duct configuration requires a bend, a certain amount of diffusion can be obtained without an appreciable rise in the total-pressure losses. If length is important, this configuration requires much less space than the usual diffuser-bend combination.

Book Description
A survey of the chromium-cobalt-nickel ternary phase diagram at 1200 degrees C was made by means of a microscopic and x-ray diffraction studies on 110 vacuum melted alloys prepared from commercial metals of the highest purity available. At 1200 degrees C, the following phases occur: (1) very extensive face centered cubic solid solutions, based on the binary cobalt-nickel solid solutions; (2) body-centered cubic chromium-base solid solutions; and (3) brittle sigma solid solutions, based on the chromium-cobalt sigma phase which is isomorphous with the iron-chromium sigma phase.
