Book Description
Runs on the zirconia-coated graphite established that the ultimate strength of this material is 30 to 100% greater than previously reported. This greater strength was apparently obtained because the gas bearings eliminate all bending moments in the specimens and the radiant heating provides more even and measurable temperatures. The ultimate strength of one pyrolytic graphite specimen was found to be over 33,600 psi at 4000 deg F. The performance of the resistance-heated furnace was very satisfactory. The gas bearings were dismounted, cleaned, plated, and are being reinstalled. Some limit switches were added to the load frame to provide protection from overtravel. (auth).

Book Description
The development of the system and techniques to permit determination of strains at right angle to the axis of loading in the specimen was continued. An additional optical system was developed to accept the lateral image of the gage points and project a vertical image of the same proportion to the apertures of the strain analyzer. Using a dummy specimen of steel in the load train, the automatic pressure control system for the gas-bearing universals was operated. A fluctuation of gas pressure occurred within the bearings. Multiple progressive fracture planes were observed throughout the gage length of fractured graphite and tungsten. (M.C.G.).

Book Description
Additional furnace work using the 25-kw induction power supply indicated reliable long-time performance at 4500 deg F. The detailed check out of the prototype, flat, gas bearing was completed. Bearing operatlon was very stable at 0.0005-in. gap. The design of the spherical bearing was begun. The grips were checked with a single graphite specimen and indicated satisfactory performance with specimen failure at the anticipated ultimate stress. The loading system was assembled, aligned, and operational check out completed. Design study of the optical strain analyzer was continued. (auth).

Book Description
Human beings undoubtedly became aware of corrosion just after they made their first metals. These people probably began to control corrosion very so on after that by trying to keep metal away from corrosive environments. "Bring your tools in out of the rain" and "Clean the blood off your sword right after battle" would have been early maxims. Now that the mechanisms of corrosion are better understood, more techniques have been developed to control it. My corrosion experience extends over 10 years in industry and research and over 20 years teaching corrosion courses to university engineering students and industrial consulting. During that time I have developed an approach to corrosion that has successfully trained over 1500 engineers. This book treats corrosion and high-temperature oxidation separately. Corrosion is divided into three groups: (1) chemical dissolution including uniform attack, (2) electrochemical corrosion from either metallurgicalor environmental cells, and (3) corrosive-mechanical interactions. It seems more logical to group corrosion according to mechanisms than to arbitrarily separate them into 8 or 20 different types of corrosion as if they were unrelated. University students and industry personnel alike generally are afraid of chemistry and consequently approach corrosion theory very hesitantly. In this text the electrochemical reactions responsible for corrosion are summed up in only five simple half-cell reactions. When these are combined on a polarization diagram, which is explained in detail, the electrochemical pro cesses become obvious.

Book Description
Integrated Gasification Combined Cycle (IGCC) Technologies discusses this innovative power generation technology that combines modern coal gasification technology with both gas turbine and steam turbine power generation, an important emerging technology which has the potential to significantly improve the efficiencies and emissions of coal power plants. The advantages of this technology over conventional pulverized coal power plants include fuel flexibility, greater efficiencies, and very low pollutant emissions. The book reviews the current status and future developments of key technologies involved in IGCC plants and how they can be integrated to maximize efficiency and reduce the cost of electricity generation in a carbon-constrained world. The first part of this book introduces the principles of IGCC systems and the fuel types for use in IGCC systems. The second part covers syngas production within IGCC systems. The third part looks at syngas cleaning, the separation of CO2 and hydrogen enrichment, with final sections describing the gas turbine combined cycle and presenting several case studies of existing IGCC plants. - Provides an in-depth, multi-contributor overview of integrated gasification combined cycle technologies - Reviews the current status and future developments of key technologies involved in IGCC plants - Provides several case studies of existing IGCC plants around the world
