The formation of slip bands is the main mechanism of cyclic deformation in pure Al. Their density, orientation and heights in polycrystalline Al were investigated during cycling. Types, sizes and densities of precipitates are responsible for the mode of cyclic deformation in AlCu4 pure alloy. In technical Al alloys intermetallic phases have detrimental effects on deformation homogeneity and largely govern the fatigue mechanism of the material and especially microcrack initiation. 相似文献

Theories with an extra spin-two field coupled to gravity admit a massive phase with broken Lorentz symmetry. While the equivalence principle is respected, the Newtonian potentials are in general modified, but they may be protected by a scale symmetry of the coupling term. The gravitational waves phenomenology is quite rich: two gravitons, one massive and one massless, oscillate and propagate with distinct velocities, different from the speed of light. A time of flight difference between gravitons and photons from a common source would provide a clear signal of this theory. 相似文献

In this note we discuss the possibility of getting a time rather than space in the scenario of (de)construction of a new dimension. 相似文献

It is believed that the detection of gamma-ray bursts from evaporating primordial black holes is highly improbable in the
near future since the expected photon flux, consisting mainly of photons with energies ≳ GeV, is too low. Contrary to this
point of view, we show that a large fraction of the black hole power at the final stage of evaporation (the last 103 s) can be liberated as a burst of soft γ-ray emission of duration 10−1–103 s and luminosity 1028–1031 erg/s in the energy range 0.1–1 MeV. According to our calculations of the black hole evaporation rate (within the Standard
Model of elementary particles), when the black hole temperature exceeds approximately 10 GeV, the charged particle outflow
from a black hole forms a well-defined plasma and can be described in the hydrodynamic approximation. In this case more than
half of the rest energy of a black hole can be converted into soft gamma-rays due to the presence of the magnetic field with
energy density comparable to that of charged particles. We consider various mechanisms leading to such transformation and
estimate their efficiency. It is shown that, at least, some of the gamma-ray bursts detected by BATSE can be associated with
evaporating black holes.

The work is devoted to the study of the LH wave effect on the peripheral plasma of the TM-1-MH tokamak. The observed enhancement of the ion saturated current in the limiter shadow is interpreted as heating of the peripheral ions by absorption of decay waves generated in this region due to the nonlinear wave-plasma interaction. 相似文献
