Gas Pressure Forming of Titanium Alloys and Composites by Transformation Superplasticity

Description: By thermally cycling through their transformation temperature range, coarse-grained, polymorphic materials can be deformed superplastically, owing to the emergence of transformation mismatch plasticity (or transformation superplasticity) as a deformation mechanism. This mechanism is investigated under biaxial stress conditions during thermal cycling of unalloyed titanium, Ti-6Al-4V, and their composites (Ti/10 vol.% TiC{sub p}, Ti-6Al-4V/10 vol% TiC{sub p} and Ti-6Al-4V/5 vol.% TiB{sub w}). Dur… more

Accuracy of the Quasistatic Method for Two-Dimensional Thermal Reactor Transients with Feedback

Description: An important aspect in the design and safe operation of a nuclear reactor is the behavior of a reactor in a transient, or nonsteady state, condition. This study shows that the quasistatic method is capable of producing highly accurate results, relative to the direct finite-difference method, for two-dimensional thermal reactor transients with feedback.

The charm quark mass to two-loop order

Description: The truncation of the perturbative series at one loop order for the mass renormalization constants remain a significant systematic uncertainty in the determination of heavy quark masses in lattice QCD. We present here a high beta Monte Carlo calculation of the two loop mass renormalization constant for clover-improved fermions near the charm mass in the Fermilab heavy quark formalism. A preliminary value for the charm quark mass in the {ovr MS} scheme at two loop order is reported.

Procedure for Determining Leachabilities of Radioactive Waste Forms

Description: Integrity and durability of solid radioactive wastes are related principally to rates at which waste constituents are leached into environmental water. This paper discusses a new and improved procedure which was developed for determining leachabilities of proposed radioactive waste forms. While no laboratory procedure can be expected to duplicate all possible environmental conditions, a single test is desirable to compare the leaching properties of solid waste forms produced in different labora… more

Hydrogen Transport in Copper

Description: Hydrogen interaction with oxygen in copper exerts a significant influence on the apparent hydrogen diffusivity and the quantity of hydrogen absorbed. Correlation of the amount of absorbed tritium with oxygen content and dependence of permeation transients on both oxygen content and prior treatment indicate that both reversible and irreversible interactions occur between hydrogen and dissolved oxygen. This paper discusses results of that study.

Some Features of Transverse Instability of Partly Compensated Proton Beams

Description: suppression of generation and accumulation of secondary particles is a traditional method for suppression the transverse electron-proton instability: improve the vacuum, use a gap in beam for electron removing, use cleaning electrodes, suppressing secondary emission. But opposite solution is also possible. Transverse e-p instability in proton rings can be damped by increasing beam density and the rate of secondary particles generation above a threshold level, with decrease of the unstable wavel… more

Small scale anisotropies of UHECRs from super-heavy halo dark matter

Description: The decay of very heavy metastable relics of the Early Universe can produce ultra-high energy cosmic rays (UHECRs) in the halo of our own Galaxy. In this model, no Greisen-Zatsepin-Kuzmin cutoff is expected because of the short propagation distances. They show here that, as a consequence of the hierarchical build up of the halo, this scenario predicts the existence of small scale anisotropies in the arrival directions of UHECRs, in addition to a large scale anisotropy, known from previous studi… more

Highly improved naive and staggered fermions

Description: We present a new action for highly improved staggered fermions. We show that perturbative calculations for the new action are well-behaved where those of the conventional staggered action are badly behaved. We discuss the effects of the new terms in controlling flavor mixing, and discuss the design of operators for the action.

E1 Working Group Summary: Neutrino factories and muon colliders

Description: We are in the middle of a time of exciting discovery, namely that neutrinos have mass and oscillate. In order to take the next steps to understand this potential window onto what well might be the mechanism that links the quarks and leptons, we need both new neutrino beams and new detectors. The new beamlines can and should also provide new laboratories for doing charged lepton flavor physics, and the new detectors can and should also provide laboratories for doing other physics like proton dec… more

Ductile Fracture of Cracked Steel Plates

Description: A simple relationship between loading for crack initiation, or onset of ductile tear, and crack length is presented for center-cracked plates of mild steel. Formulation of the nonlinear boundary-value problem is based on incremental theory of plasticity for Prandtl-Reuss materials. Quasi-static solutions corresponding to a series of incremental loading conditions are obtained by the method of finite elements. Tests conducted on plates of two types of mild steel agree with numerical results.

HyperCP at Fermilab -- A status report

Description: The primary purpose of the HyperCP experiment at Fermilab is to test CP in hyperon decays by comparing the alpha parameters for {Xi}{sup -} and {Xi}{sup +} decays in the decay sequence: {Xi}{sup -} {yields} {pi} + {Lambda}{sup 0}, {Lambda}{sup 0} {yields} {pi}{sup -} + p. In addition, we can test CP in charged kaon decays by comparing the slopes of the Dalitz plot for K{sup +} and K{sup -} decays. They are also looking at rare decay modes of charged kaons and hyperons, particularly those involv… more
