Erratum: Deformation Peaks in Alpha Zirconium

High Pressure Deformation Study of Zirconium

In situ deformation studies of polycrystalline materials using diffraction are an established method to understand elastic and plastic deformation of materials. Studies of active deformation mechanisms, the interplay of deformation with texture and ultimately the development of predictive capabilities for deformation modeling are an active field of research. Parameters studied by diffraction ar...

Transformation from slip to plastic flow deformation mechanism during tensile deformation of zirconium nanocontacts

Various types of nanometer-sized structures have been applied to advanced functional and structural devices. Inherent structures, thermal stability, and properties of such nanostructures are emphasized when their size is decreased to several nanometers, especially, to several atoms. In this study, we observed the atomistic tensile deformation process of zirconium nanocontacts, which are typical...

The b Distribution and the Velocity Structure of Absorption Peaks in the Lyman - Alpha Forest

A theory is developed which relates the observed b-parameter of a Lyα absorption line to the velocity-curvature of the corresponding peak in the optical depth fluctuation. Its relation to the traditional interpretation of b as the thermal broadening width is discussed. It is demonstrated that, independent of the details of the cosmological model, the differential b distribution has a high b asy...

On the Origin of the Satellite Peaks in Alpha Particle Spectra

In this work we describe the results obtained with S3590-06 and ion-implanted diodes for alpha particle spectrometry. Satellite peaks were also investigated in order to identify not only the origin of these phenomena, but also the importance of the guard ring region on their relative intensities. The preliminary results indicate that the true cause of the spurious satellite peaks might be assoc...
