Critical current distributions and the V(1) transition in Nb-Ti superconducting composites

Creator:: Narang, Girish
Abstract:: It is well established that the extended range V(I) transition behavior in filamentary superconducting composites depends strongly on the processing conditions of the composite. Based on previous work, a model proposed by Warnes et al predicts that the second derivative of the V(I) transition is related to a more fundamental...

Characterization of TiNbHf alloys for potential medical dental applications

Creator:: Amick, Darryl D.
Abstract:: A series of TiNbHf alloys ranging from 0-40 atomic % Nb and 0-15 atomic % Hf were evaluated to investigate low-elastic modulus phenomena which occur in this ternary system. The desirability of utilizing corrosion-resistant, biocompatible alloys with elastic modulus values approaching that of human bone for medical prosthetic implants provides...

Design of advanced aluminum silicon alloy compositions and processing

Creator:: Li, Xiao, 1963-
Abstract:: Part I discusses the development of an aluminum-magnesium-silicon alloy that may combine strength, extrudability, favorable corrosion resistance with low cost and scrap compatibility. The first part of the study determined the effects of small composition, heat treatment and mechanical processing changes on the ambient temperature tensile properties of the alloy....

Dwell time low cycle fatigue in Ti-6242Si

Creator:: Faber, Robyn O.
Abstract:: Dwell time low cycle fatigue (DLCF), low cycle fatigue (LCF), and creep tests were performed at ambient temperature on Ti-6Al-2Sn-4Zr-2Mo-0.1Si (Ti-6242Si). Test specimens were solution annealed at various temperatures below the beta transus to control the volume fraction of primary alpha. The influence of the changes in primary alpha phase...

Seedling and site interactions

Creator:: Hobbs, Stephen D.
Resource Type:: Part of Book
Full Text:: synthesis of a wide array of organic and inor- ganic compounds necessary to seedling physiology. For example

Patterns of xylem variation within a tree and their hydraulic and mechanical consequences

Creator:: Gartner, Barbara L.
Abstract:: Xylem is nonuniform in its structure and function throughout the plant stem. Xylem structure varies from pith to bark, from root to apical meristem, from stem to branch, at nodes vs internodes, and at junctions of branches, stems or roots compared to the internodal regions nearby. At smaller scales, anatomy...

Radiation effects in compound semiconductor heterostructure devices

Creator:: Sarkar, Aveek, 1974-
Abstract:: Radiation studies were performed on compound semiconductor heterostructure devices. The objective was to understand the degradation processes caused by the exposure of these devices to radiation. Preliminary experiments were focussed on studying the degradation phenomenon in single heterojunctions and single quantum wells. It was found that ionizing radiation like gamma...
