The variation of subgrain misorientation in aluminum with large steady-state creep strain
High purity aluminum was torsionally deformed to various strains up to 16.33 at a temperature of 644 K in this study. The variation in the dislocation substructure was determined with increasing strain. Recent work revealed ...
Nucleate pool-boiling of R-114 refrigerant and oil mixtures from water-heated enhanced surfaces
Heat- transfer measurements were made for a single, water-heated tube in a pool of R-114 to simulate operating conditions of a water chiller. Data were obtained for a smooth copper tube, and for two commercially ...
A parametric study of elastic response of submarine-installed equipment subjected to UNDEX side-on loading
It is desirable to perform a study of the elastic responses of submarine hulls and internally attached structures to underwater shock loading. In view of the expense and possible involvement of non-shock testable equipment ...
An analysis of the performance of a vertically oriented, gas loaded, variable conductance heat pipe
An analysis of steady state operation of a vertically oriented, variable conductance heat pipe is presented. The effects of binary mass diffusion, axial pipe wall conduction, and gravitational effects, caused by the ...
An investigation into the tripping behavior of longitudinally T-stiffened rectangular flat plates loaded statically and impulsively
An experimental investigation was conducted to determine the static and dynamic responses of a specific stiffened flat plate design. The air-backed rectangular flat plates of 6061-T6 aluminum with an externally machined ...
An investigation of the oxide adhesion and growth characteristics on platinum modified aluminide coatings.
The operating environment for superalloy blades and vanes in gas turbine engines has necessitated the development of alloy coatings to achieve satisfactory resistance of the metal to oxidation and hot corrosion. Aluminide ...
Film condensation of steam on externally enhanced horizontal tubes
(Monterey, California: U.S. Naval Postgraduate School, 1986)
The effect of thermomechanical processing variables on ductility of a high-Mg, Al-Mg-Zr alloy.
In previous research on thermomechanically processed high - Mg, \1 - Mg alloys, yield strengths of 276 MPa (40 ksi) were retained after simulated superplastic forming, but ductility at ambient temperature varied from ...
