Long-term ageing characteristics of Hastelloy alloy X

Abstract: Transmission electron microscopy and diffraction were used to characterize the microstructural changes which occur in Hastelloy alloy X after long-term ageing (up to 16 000 h) at various temperatures in the range 540 to 870° C. The corresponding effects on mechanical properties were determined. It was found that the alloy age hardens at temperatures in the range of 650 to 870° C. Overageing occurred at 760 and 870° C. Marked reductions in room-temperature tensile elongation were observed after ageing at all the temperatures investigated. However, in no case was the elongation reduced to less than 15 to 30%. Also, the tensile elongation at temperatures corresponding to the respective ageing temperatures was unaffected by 16 000 h ageing at a temperature. It was concluded that the above effects were associated with precipitation of various phases, such as carbides, sigma- and mu-phases, in the matrix and at the grain boundaries.

Process for making non-porous, micron-sized high purity silica

Abstract: A process for making non-porous, dense, silica particles having a diameter of about 3 to 1000 microns, a nitrogen B.E.T. surface area less than about 1 m2/g, a total impurity content of less than about 50 ppm and a metal impurity content of less than about 15 ppm from an aqueous dispersion of fumed silica. The particles are converted into porous particles and sintered in an atmosphere having a water partial pressure of from about 0.2 to about 0.8 atmosphere for temperatures below about 1200 °C.

Process for uniformly moisturizing fumed silica

Abstract: An improved process for uniformly distributing high levels of water in hydrophilic fumed silica by mixing with dry water.

Modified carbon products and their applications

Abstract: Modified carbon products including a metal group attached to the modified carbon product. The modified carbon products are particularly useful for various applications such as catalysis, electronic conduction, ionic conduction, absorbents, heat transfer and luminescence.
