FEASIBILITY DEMONSTRATION OF A TRANSPIRATION COOLED NOZZLE SYSTEM (2006)
Smith, K. J., Poulos, E. N., Steigerwald, E. A., Lally, F., Peck, J. V., Pappas, C.
The use of transpiration cooling for advanced solid propellant application is described. The mechanism used for demonstration purposes consisted of a porous tungsten insert cooled by anhydrous...
Faulkner,J. M., Hanna,G. L., Peck,J. V.
A research program was conducted to develop welding procedures and filler materials for joining a martensitic and a bainitic steel having yield strengths of 180 to 200 ksi with adequate ductility and...
Development of Repair and Reprocess Coatings for Air-Cooled Nickel Alloy Turbine Blades. (2005)
The purpose of this program was to identify, develop and characterize coating compositions, processing techniques and resulting properties for: (1) repair of localized damage to diffused aluminide...
Faulkner, J. M., Hanna, G. L., Peck, J. V.
The object of this program was to develop welding procedures and filler materials for joining martensitic and bainitic steels in the 180 to 200 ksi yield strength range. Martensitic steels studied...
MICROSTRUCTURAL - MECHANICAL PROPERTY RELATIONSHIPS IN HIGH STRENGTH CAST STEELS. (1998)
Peck,J. V., Bertolo,R. B., Wallace,J. F.
The grain refinement of high strength steel castings by small titanium additions has been enhanced by a small particle nucleation technique. The combination of these two mechanisms makes possible the...
The purpose of this program was to develop welding procedures for joining martensitic and bainitic steels in the 180 to 200 ksi yield strength range. The martensitic steel, HP 9-4-25, was automatic...
