Continuing Appropriations Acts: Brief Overview of Recent Practices
This report provides information on the history of continuing resolutions; the nature, scope, and duration of CRs during the last 30 years; the various types of CRs that have been enacted; and an overview of those instances when budget authority has lapsed and a funding gap has resulted.
Shutdown of the Federal Government: Causes, Effects, and Process
This report provides a brief overview of the causes and effects of federal government shutdowns. This report provides a brief overview of the causes and effects of federal government shutdowns. When federal agencies and programs lack appropriated funding, they must cease operations, except in emergency situations. The failure of the President and Congress to reach agreement on funding measures has caused government shutdowns. It is necessary either to enact temporary funding legislation at the close of the fiscal year or to shut down the activities that are not funded at that time.
Powder Metallurgy Repair of Turbine Components
An advanced powder metallurgy repair process called Liburdi Powder Metallurgy (LPM) has been developed for the repair, overlay or joining of nickel and cobalt-based high-temperature alloys. This process involves mechanical cleaning, followed by the application and consolidation of a filler metal powder, which has substantially the same composition as the base metal, and producer joints with mechanical properties similar to those of the parent material. While previously activated braze or wide-gap'' repair processes have been limited to clearances of approximately 1 mm, the LPM technique has the ability to bridge larger gaps of over 5 mm. In addition, the LPM joints contain significantly lower concentrations of melting point depressants such as silicon and boron than conventional wide-gap repair techniques and exhibit superior microstructural features. The characteristics and typical applications of the LPM process for blade and vane repairs are highlighted and the results of laboratory and engine tests are discussed.
