Solid particle erosion of hard anodised and uncoated 6061–T651 aluminium alloy

Autor: K. Elliot, J. L. Routbort, K. R. Karesk, R. G. Rateick

Publikováno v: Materials Science and Technology. 13:217-222

The solid particle erosion resistance of hard anodised 6061–T651 aluminium alloy was determined at room temperature using slinger erosion apparatus. Experimental conditions were chosen to represent erosion in gas turbine engine fuel systems. This s

Degradation of structural ceramics by erosion

Autor: J. L. Routbort

Publikováno v: Journal of Nondestructive Evaluation. 15:107-112

Materials wastage by solid-particle erosion can be severe and limit lifetimes. This paper will review the theoretical description of solid-particle erosion in brittle materials, which is well-developed for monolithic ceramics. The models can usually

Atomic transport of oxygen in nonstoichiometric oxides

Autor: J. L. Routbort, G. W. Tomlins

Publikováno v: Radiation Effects and Defects in Solids. 137:233-238

Atomic transport of oxygen in nonstoichiometric oxides is an extremely important topic that overlaps science and technology. In many cases, diffusion of oxygen controls sintering, grain growth, and creep. High oxygen diffusivity is critical for effic

Oxygen diffusion in cuprate superconductors

Autor: J. L. Routbort, S. J. Rothman

Publikováno v: Journal of Applied Physics. 76:5615-5628

Superconducting properties of the cuprate superconductors depend on the oxygen content of the material; the diffusion of oxygen is thus an important process in the fabrication and application of these materials. In the present article, we review stud

Tracer diffusion of Ag in Bi2Sr2Can−1CunO2n+4

Autor: J. L. Routbort, Y. Fang

Publikováno v: Journal of Applied Physics. 75:210-215

Tracer diffusion of Ag in the c direction of single crystal Bi2Sr2CaCu2Ox (2212), and in dense polycrystalline Bi2Sr2CuOx (2201) and (Bi,Pb)2Sr2Ca2Cu3Ox (2223) has been investigated. Concentration profiles were measured by secondary‐ion mass spectr

Pressure drop, heat transfer, critical heat flux, and flow stability of two-phase flow boiling of water and ethylene glycol/water mixtures - final report for project 'Efficent cooling in engines with nucleate boiling.'

Autor: W. Yu, D. M. France, J. L. Routbort

Because of its order-of-magnitude higher heat transfer rates, there is interest in using controllable two-phase nucleate boiling instead of conventional single-phase forced convection in vehicular cooling systems to remove ever increasing heat loads

Publikováno v: Superconductor Science and Technology. 5:634-639

Microstructure and microchemistry characterizations have been made using analytical transmission electron microscopy in order to correlate extended defect formation to intergranular and intragranular current density values. AC magnetization curves as

Fracture toughness of YBa2Cu3Oxcontaining Y2BaCuO5and ZrO2

Autor: M. L. Kullberg, J L Routbort, K.C. Goretta, G A Risch, D Bar

Publikováno v: Superconductor Science and Technology. 4:544-547

Tetragonal ZrO2 particles have been added to superconducting YBa2Cu3Ox(123) to improve its fracture toughness (KlC). Reactions between the ZrO2 and 123 prevented the ZrO2 from providing significant toughening. A sol-gel coating of Y2BaCuO5(211) on th
