Influence of phase transition on shock-induced spallation in nanocrystalline iron
(American Institute of Physics, 2015-11)
Intense shock waves may lead to spallation of the sample. Recent experiments show differences of shock spallation in iron depending on whether the samples underwent the pressure-induced bcc-hcp phase transformation or not. ...
Phase transformation studies in U–Nb–Zr alloy.
(Amsterdam, 2013-12)
Phase transformation diagrams provide fundamental informations for designing thermomechanical processes being a must regarding uranium alloys nuclear fuels. The work shows the evaluation of a kinetic transformation diagram ...
Non-transposed three-phase line analyses with a single real transformation matrix
(2005-10-31)
In transmission line transient analyses, a single real transformation matrix can obtain exact modes when the analyzed line is transposed. For non-transposed lines, the results are not exact. In this paper, non-symmetrical ...

Single real transformation matrices applied to double three-phase transmission lines
(Elsevier B.V. Sa, 2008-10-01)
Single real transformation matrices are tested as phase-mode transformation matrices of typical symmetrical systems with double three-phase and two parallel double three-phase transmission lines. These single real ...

Uniform sparse bounds for discrete quadratic phase Hilbert transforms
(2017-09)
Consider the discrete quadratic phase Hilbert Transform acting on $\ell^{2}(\mathbb{Z})$ finitely supported
functions
$$
H^{\alpha} f(n) : = \sum_{m \neq 0} \frac{e^{i\alpha m^2} f(n - m)}{m}.
$$
We prove that, ...

Phase transformations in the Cu-Al alloy with Ag addition
(2005-05-18)
The effect of Ag addition on the phase transformations that occur in the Cu-10% Al alloy was studied using differential thermal analysis, scanning electron and optical microscopies and energy dispersive X-ray analysis. The ...
