Oxidation-resistant interfacial coatings for fiber-reinforced ceramic composites

Description: A ceramic-matrix composite having a multilayered interfacial coating adapted to protect the reinforcing fibers from long-term oxidation, while allowing these to bridge the wake of advancing cracks in the matrix, is provided by selectively mismatching materials within adjacent layers of the interfacial coating, the materials having different coefficients of thermal expansion so that a low toughness interface region is created to promote crack deflection either within an interior layer of the mis… more

Excise Taxes on Alcohol, Tobacco, and Gasoline: History and Inflation-Adjusted Rates

Description: This report provides inflation-adjusted excise tax rates for alcohol, tobacco, and gasoline products. The base for computation is November 1951. All of the above cited commodities had rate increases effective for that date under the Revenue Act of 1951. The adjustments show what the tax rates would be in 1999 if they had been increased to reflect inflation

A Convergence Analysis of Unconstrained and Bound Constrained Evolutionary Pattern Search

Description: The authors present and analyze a class of evolutionary algorithms for unconstrained and bound constrained optimization on R{sup n}: evolutionary pattern search algorithms (EPSAs). EPSAs adaptively modify the step size of the mutation operator in response to the success of previous optimization steps. The design of EPSAs is inspired by recent analyses of pattern search methods. They show that EPSAs can be cast as stochastic pattern search methods, and they use this observation to prove that EpS… more

Heat Treat of 3Z Valve Piston

Description: To improve the processing of 3Z valve pistons in LF7 assemblies, material qualities are being investigated. After a review of the fracture toughness curve, it was noted that a change of a few degrees variation from the 900 F called for by the drawing would affect the fracture toughness of the product. After this observation it was decided to determine how close to the 900 F the parts were heat-treated. The subsequent study indicated that Federal Manufacturing & Technologies (FM&T) equipment… more

Room-temperature laser action at 4.3--4.4 {micro}m in CaGa{sub 2}S{sub 4}:Dy{sup 3+}

Description: The authors report room-temperature mid-IR laser operation in a new low-phonon-frequency, non-hygroscopic host crystal CaGa{sub 2}S{sub 4} (calcium thiogallate). Laser action at 4.31 {micro}m on the {sup 6}H{sub 11/2} {r_arrow}{sup 6}H{sub 13/2} transition of trivalent dysprosium was achieved with a slope efficiency of 1.6%.

In-situ, real-time, studies of film growth processes using ion scattering and direct recoil spectroscopy techniques.

Description: Time-of-flight ion scattering and recoil spectroscopy (TOF-ISARS) enables the characterization of the composition and structure of surfaces with 1-2 monolayer specificity. It will be shown that surface analysis is possible at ambient pressures greater than 3 mTorr using TOF-ISARS techniques; allowing for real-time, in situ studies of film growth processes. TOF-ISARS comprises three analytical techniques: ion scattering spectroscopy (ISS), which detects the backscattered primary ion beam; direct… more
