Optimum Application

A new modification of an economical casting material is presented for use in the intermediate temperature range, which is considered to be 800 to 1300 F. An illustration is given of two large castings actually produced for the 1500-hp ATAC regenerative gas turbines engine. Comparisons are made with other materials, giving information stress-rupture at various temperature levels and some cost information. Also included are design suggestions for better utilization of foundry techniques.

Critical Components

The Closed Cycle Gas Turbine (CCGT) offers potential savings in operating costs due to high system efficiency and the ability to direct fire coal. However, for the full potential of CCGT to be realized, more competitive cost information must be generated, correlated, and compared with conventional steam power systems. Current development programs are intended to resolve many of the remaining uncertainties in design, performance, and cost by detailed examination and testing of critical components of CCGT coal-fired power systems. This paper reviews current technology developments and economic considerations of the closed cycle gas turbine burning dirty fuels versus conventional steam power systems.

AbstractThe deformation behavior of MoSi2 single crystals has been studied in the temperature range of -196<1500°C. While [001]-oriented crystals can be plastically deformed only above 1300°C, plastic flow is possible from temperatures as low as room temperature for single crystals with orientations other than [001]. Five slip systems, {110)<111], {011)<100], {010)<100], {023)<100] and {013)<331], are identified to be operative, depending on crystal orientation. An anomalous increase in CRSS is observed in the intermediate temperature range for the former three slip systems. Schmid’s law is generally valid for the soft modes, {110)<111], {011)<100] and {023)<100]. In contrast, the CRSS for the hard mode, {013)<331], strongly depends on crystal orientation with the higher values for orientations closer to [001].
